 ## 0.1.N MVP UI And UX
 
 - [x] Add main menu placeholder. Added native `UAgrarianMvpFrontendWidget` with a scalable painted main menu panel and local player-controller spawning so the MVP frontend has an owned placeholder instead of relying on template UI.
-- [ ] After splash/startup screens, land on an MVP character selection landing page.
+- [x] After splash/startup screens, land on an MVP character selection landing page. The local player controller now opens the MVP frontend on `CharacterSelection`, and the native frontend widget paints a scalable character-selection landing page before gameplay.
 - [ ] Let players choose a realistic young adult male or female character with average proportions for the MVP.
 - [ ] Add join server screen.
 - [ ] Add loading screen.
