The F9 audit found TLC had no Appearance dialog — the Skins...
dialog was the only appearance option. MC's CK_OptionsAppearance
offers five checkbox toggles plus a skin selector.
Create AppearanceDialog with 6 rows:
- Menubar (show/hide F9 menu bar)
- Keybar (show/hide F1-F10 key hint bar)
- Hint bar (show/hide status bar)
- Command prompt (show/hide command-line prompt)
- Mini status (show/hide mini-status above keybar)
- Skins... (opens the existing SkinDialog)
All five toggles write back to RuntimeConfig's show_* fields.
Enter toggles the checkbox; Esc dismisses; Skins... opens the
skin selection dialog transparently.
Added to F9 → Options menu as 'Appearance...' between
Confirmation and Skins, matching MC's menu ordering.
Added 4 unit tests: toggles default true, enter toggles off/on,
down cycles cursor, skin button opens skin outcome.
Tests: 1411 pass (was 1407), zero warnings.
