TCNOco/TcNo-Acc-Switcher ? reverse-engineered prompt

Build me a fast desktop app that helps me switch between multiple accounts for game launchers and related apps like Steam, Battle.net, Epic Games, Origin, Riot, Ubisoft Connect, Discord, and a few others.

I want it to feel simple and quick, with a clean main window, tray access, and a nice themeable interface. It should let me add accounts, switch between them without re entering passwords every time, and handle the usual account data by swapping the right local files and settings while the app is closed. Please include support for Steam extras like offline or invisible status, quick launch shortcuts, and optional Steam Guard handling, but make that clearly separate and optional.

It should not store passwords unless I explicitly choose to, and it should be transparent about what it changes. If you need current platform details or docs while building, look them up online. Make it work on Windows first, and keep the structure easy to extend so new platforms can be added later.
