Build me a minimalist desktop app for managing a personal game library, mainly for visual novel style games.

I want to point it at a messy games folder and have it automatically clean everything up into a nice grid with real game titles, icons, and the right executable hidden inside subfolders. From there I should be able to double click a game to launch it, see playtime for each one, and keep everything organized without digging through File Explorer.

It should also be able to find save folders automatically on Windows and Linux, including weird locations like AppData, Ren Py folders, Linux config paths, and Wine or Proton prefixes. I want a built in save editor for common game engines like RPG Maker, Ren Py, Unity, and Wolf RPG, with simple controls for editing things like gold, variables, and switches.

If it makes sense, add one click setup for translation patches too. Make it feel clean, lightweight, and practical, with a minimalist UI and support for both Windows and Linux.
