    • Added configurable keyboard shortcuts for cine mode, overlays, overlay navigation, and metadata visibility.
    • Shortcuts can be edited, reset individually, or restored to defaults in Settings.
    • Added validation for duplicate, reserved, invalid, and unsupported key assignments.
    • Shortcut settings persist in desktop builds and remain session-only in browser builds.
    • Interface labels reflect current shortcut assignments.
    • Reset all now also restores visible metadata field selections.

📝 Walkthrough

Walkthrough

The application now supports configurable shortcuts for cine mode, overlay toggling, overlay navigation, and metadata visibility. Desktop settings persist shortcut bindings. Invalid or conflicting bindings use safe defaults. Browser builds keep changes session-only.

Changes

Configurable keyboard shortcuts

Layer / File(s) Summary
Shortcut contracts and persistence
src/app.rs, DESIGN.md
Defines shortcut actions and defaults, validates assignable and unique keys, serializes settings, restores valid bindings, and falls back when persisted bindings conflict.
Settings UI and key capture
src/app.rs
Adds shortcut controls, reset actions, capture state, validation errors, Escape cancellation, Shift rejection, and tests for capture, conflicts, persistence, and resets.
Runtime actions and labels
src/app.rs, src/app/metadata.rs, README.md, CITATION.cff
Uses configured shortcuts for application actions and metadata labels. Documentation describes defaults and reset behavior. Citation text references research use and the preferred citation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 347d9

Configurable shortcuts may trigger unexpectedly when Shift or Alt is held, and Reset All may leave metadata field selections unchanged. These bounded correctness issues should be fixed or explicitly accepted before merging.

3332-3348: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Require exact no-modifier matches for configurable shortcuts.

consume_key(egui::Modifiers::NONE, key) uses logical matching, so extra Shift and Alt modifiers still match. A configured P shortcut can therefore run for Shift+P or Alt+P, although capture rejects modifier combinations. Check input.modifiers.matches_exact(egui::Modifiers::NONE) before consuming these shortcuts, and add coverage for both cases.

1216-1225: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reset metadata field selections in reset_all_settings.

visible_metadata_fields is persisted in AppSettings, but Reset all only resets the color and shortcuts. After a user changes metadata fields, Reset all leaves that setting unchanged. Restore default_visible_metadata_fields() here and extend the reset test.
