Summary
In
Panesdisplay granularity, the vertical tab bar only rendered a tab-group header when the tab had a user-set custom title or was being renamed inline. Multi-pane tabs with auto-generated names therefore showed no tab-level identifier at all — only the first row's pane title was visible, making every such tab look identical in the sidebar (upstream report: warpdotdev#9098).This extracts the header gate into a testable
should_show_tab_group_headerhelper and adds a third trigger: any tab with more than one visible pane now renders its group header. Single-pane groups without a custom title still omit the header, since the lone row already shows the same title and rendering it twice would duplicate the text.Changes
app/src/workspace/view/vertical_tabs.rs: newshould_show_tab_group_header(has_custom_title, is_being_renamed, visible_pane_count)helper; header now renders for multi-pane groups.app/src/workspace/view/vertical_tabs_tests.rs: 5 regression tests covering the gate (custom title, inline rename, multi-pane without title, single-pane suppression, and the multi-tab scenario from the original report).Testing
cargo test -p warp vertical_tabs— all 5 new tests pass; the 9 pre-existing failures in that filter reproduce identically on cleanmain(test-harness singleton/i18n setup issues, unrelated to this change).
