Added a desktop app with Library, Browse, Updates, and Settings screens, including mod search, installation and update controls, account management, and light, dark, or system themes.
Added mod preview images in browse and library views.
Added Linux AppImage, Deb, and RPM packaging.
Updates
The README now covers both the desktop app and command-line tool, including launch and packaging instructions.
Bug Fixes
Improved display of mod images and library status details.
Library, Browse, Updates and Settings screens as in the design, light and dark.
AppModel holds the state on top of ModManager; what the Library and Updates
screens show is derived in LibraryData (unit tested). Installs run one at a
time with download progress and cancel; mod.io subscribe/unsubscribe and the
mod.io and modwerkstatt.com sign-ins work from the app.
transportfever.net (images.preview), modwerkstatt.com (image_url) and mod.io
(logo) pictures go through a new ImageCache in core: HTTPS only, at most 5 MB
each, 4 at a time, kept in ~/.cache/shunter/images and pruned after 30 days.
The Library shows the mod.io logo for Mod Hub mods, which have no preview.
Also fixes the Library preview keeping the first mod's picture when the
selection changed: the image state was not keyed by the mod.
The pull request adds a Compose Desktop app with library, browse, updates, and settings screens. It adds application state, logging setup, preview-image caching and display, theme support, and desktop packaging configuration.
The project includes the app and logging modules, configures Compose Desktop and Linux packages, and adds desktop launch options. The README and development notes describe the app, and the CLI now uses the logging module.
Feed and mod.io data expose image URLs. The core adds bounded image downloads, persistent caching, and pruning. The app loads previews asynchronously and displays local or remote images.
Application state and library status app/src/main/kotlin/ch/lightspots/shunter/app/AppModel.kt, app/src/main/kotlin/ch/lightspots/shunter/app/Status.kt, app/src/main/kotlin/ch/lightspots/shunter/app/Format.kt, app/src/test/kotlin/ch/lightspots/shunter/app/*
AppModel coordinates scans, feeds, installs, updates, accounts, and navigation. LibraryData derives mod status and problems. Formatting and tests cover displayed values and status conditions.
Theme and shared Compose components app/src/main/kotlin/ch/lightspots/shunter/app/ui/Theme.kt, app/src/main/kotlin/ch/lightspots/shunter/app/ui/Components.kt, app/src/main/kotlin/ch/lightspots/shunter/app/ui/Icons.kt, .editorconfig
The app adds light and dark themes, typography, icons, and reusable UI components. The editor configuration exempts composable functions from the function-naming rule.
Desktop screens and user interactions app/src/main/kotlin/ch/lightspots/shunter/app/ui/App.kt, app/src/main/kotlin/ch/lightspots/shunter/app/ui/BrowseScreen.kt, app/src/main/kotlin/ch/lightspots/shunter/app/ui/LibraryScreen.kt, app/src/main/kotlin/ch/lightspots/shunter/app/ui/UpdatesScreen.kt, app/src/main/kotlin/ch/lightspots/shunter/app/ui/SettingsScreen.kt, README.md, CLAUDE.md
The screens present library contents, browse results, updates and problems, account controls, theme selection, and folder actions.
Lightspots/shunter#15: Adds the ModWerkstatt sign-in APIs and feed sign-in status used by the app model and settings screen.

Explanation
The title "#16 ✨ desktop app" is related to the main change. The PR adds a Compose Desktop app with Library, Browse, Updates, and Settings screens, and it resolves issue #16. The title is short and names the primary change, but it is terse. It starts with an issue number and an emoji, and it does not name the feature more specifically. The title is not unrelated and not vague, so it passes.
Full details: Linked Issues check
Explanation
Directly linked open issue #16 requires implementing the desktop app, with its UI following the linked design. The PR summary shows the required implementation at head: a new app Gradle module with Compose Desktop build configuration and entry point (app/build.gradle.kts, Main.kt); the four requested screens (LibraryScreen.kt, BrowseScreen.kt, UpdatesScreen.kt, SettingsScreen.kt); sidebar navigation and message overlay (ui/App.kt); light and dark themes (ui/Theme.kt); app state and install serialization with progress and cancellation (AppModel.kt); library status model (Status.kt); and :app included in settings.gradle.kts. Unit tests cover LibraryData (LibraryDataTest.kt) and formatting helpers (FormatTest.kt). The issue sets no further measurable acceptance criteria. Limits: the linked design artifact is an external URL that this review could not open, so pixel-level conformance to that design was not verified. The UI tests and visual behavior were not executed in this review. Based on the summarized code, the coding requirement is met.
Full details: Out of Scope Changes check
Explanation
Changes outside app/ relate to the desktop app or its direct needs. (1) Logging: the new logging module, its move from the cli package, and the cli dependency change support shared frontend logging, which the app startup uses. (2) Preview images: ImageCache, HttpDownloader.fetchBytes, AppDirs.images, ModManager.images, RemoteMod.imageUrl, ModIoMod.logoUrl, and the TFNet/ModWerkstatt parser changes supply thumbnails for Library and Browse rows, which the app's Thumbnail and image components consume. Their tests (ImageCacheTest, FeedParsersTest, ModIoClientTest) cover these changes. (3) Build and tooling: gradle/libs.versions.toml (Material 3, Swing coroutines for Dispatchers.Main), settings.gradle.kts, and .editorconfig (Composable naming exemption for ktlint) support the new Compose code. (4) Documentation: README.md and CLAUDE.md describe the app, its views, launch and packaging commands, and logging behavior. Mod.io and ModWerkstatt sign-in and mod.io subscribe/unsubscribe appear in the Settings and Browse screens that the issue requires. No change was found that lacks a connection to the desktop app. The CLAUDE.md statement about 404 image responses as of 2026-11 is documentation text and was not verified here.

Bound decoded image dimensions before preview pixels are materialized.
Previews.load decodes the whole picture at line 86 before any size check. scaled caps only the width. The output height follows the source aspect ratio and has no limit. The 5 MB ImageCache limit applies to encoded bytes, and local _metadata/0.png files have no size limit at extraction. A small compressed PNG can decode to a very large raster. This affects remote previews from the Browse list and local previews from the Library list. A large allocation can exhaust native memory or stall the app.
Suggested change
Read the image header dimensions before the full decode. Reject the preview when width * height exceeds a fixed pixel limit. Apply the same limit to the scaled output size before Surface.makeRasterN32Premul runs. Return null for a rejected image, as the existing failure path does.

Serialize theme saves so the last selection is written last.
updateTheme starts one independent Dispatchers.IO job for each selection. The IO dispatcher runs these jobs in parallel, and no lock or ordering guard covers them. If an older save finishes after a newer one, the older theme stays in app.properties, and the next launch restores it. Overlapping outputStream() writes can also interleave bytes in the file.

Remove the partial .part file when a preview download fails.
When writeBytes or moveTo throws after the .part file is created, the catch block records the URL as failed but leaves <name>.part on disk. The file is not reused in this session. Startup pruning removes it only after it exceeds the 30-day age limit, or the next successful fetch of that URL overwrites it.
Declare part before the try block. The catch block can then reference it. Run the cleanup on Dispatchers.IO, because this is a suspend function.

Refresh the library when a multi-file install fails or is cancelled after a file is committed.
Each completed file writes its mod folder and install record. When a later file fails or is cancelled, the catch branches in install skip refreshLibrary(). Library and Updates then show old versions until a rescan or feed refresh. Call refreshLibrary() on both paths. Launch the cancellation refresh in scope, because the cancelled operation coroutine cannot wait in job.join().

Launcher.open returns true as soon as xdg-open starts. When xdg-open then exits non-zero, for example when no handler exists, AppModel.openFolder and AppModel.openUrl show no error. Check the exit status without blocking the UI thread, because a successful xdg-open launch may keep running for a long time.
Possible approach
Wait for the process on a background thread. Report a non-zero exit through showError. Remove the true return that implies success before the exit status is known.

Show an unknown status until the mod has been checked.
Before its feed loads, or if loading fails without a cached copy, a feed-installed mod is labeled “Up to date” even though its update status is unknown. Track whether the mod was checked and show an unknown status until a comparison is available.

Update the status logic in Status.kt so feed-installed mods show an unknown
status until their update comparison has completed; do not label them “Up to
date” merely because record?.origin?.source is non-null. Track whether the mod
has been checked, including when the feed is still loading or failed without a
cached copy, and preserve the existing “Up to date” and “From archive” statuses
once their conditions are established.

Reset the local preview state when a rescan runs.
After Rescan, a row or the details pane for an unchanged mod keeps the picture it loaded before the scan. rememberLocalImage keys its remember state and its LaunchedEffect only on path and maxWidth. Previews.clear() empties the cache but does not change this state. The state.value == null guard then skips the reload while the old picture is held. The stale picture remains until the row leaves composition or the selection changes.
Add a value that changes on each rescan as a parameter of rememberLocalImage. Use it in both the remember key and the LaunchedEffect key. Changing only the remember key does not restart the load, because the effect keeps its original keys.

Update rememberLocalImage to accept a value that changes on each rescan, and
include it in both the remember key and the LaunchedEffect key so local preview
state is recreated and the image load restarts after a rescan. Pass the existing
rescan-changing value from its caller.

Make the size assertion locale-aware.
When the test JVM uses a comma-decimal locale, humanSize returns 14,2 MB, so this assertion fails. Use a locale-aware expectation or set a known locale for the test process.

Review comment at @app/src/test/kotlin/ch/lightspots/shunter/app/FormatTest.kt
at line 14:
Update the humanSize assertion in FormatTest to avoid assuming a decimal point:
either derive the expected value using the active locale or set and restore a
known locale for the test so it is isolated from the test JVM’s locale.
