+## 2025-05-14 - [Flet Dialog Accessibility & Pulse Indicators]
+**Learning:** Dialogs in this Flet-based app often lack automatic focus and Enter-key submission, creating friction for keyboard-driven "Quick Recording" workflows. Additionally, static status labels for long-running tasks (like recording) benefit significantly from subtle animations to provide glancing feedback.
+**Action:** Always ensure `autofocus=True` and `on_submit` are set for primary inputs in dialogs. Use `animate_opacity` in conjunction with existing periodic update tasks (like duration timers) to create lightweight, "alive" visual indicators.

+## 2025-05-14 - [Config Performance Optimization]
+**Learning:** The `ConfigManager` was performing synchronous disk I/O on every configuration value lookup via `get_config_value`. While individually fast, these operations aggregate and block the event loop in an `asyncio` application, potentially causing micro-stutters in the UI.
+**Action:** Implement memory caching in `ConfigManager` to ensure that subsequent reads are served from RAM, and only write-through to disk when settings are modified.
