Stage Manager for Windows
macOS Stage Manager on Windows: one app on screen, the rest tucked into cards at the edge.

About
A Windows 10 and 11 window manager modeled on macOS Stage Manager, drawn with MyGo's native UI. Each monitor keeps the app in use on its stage and groups the rest by app into cards on the left or right edge; click a card to switch, Shift-click it for two apps side by side, or press Win+Tab to see every window. Alt+Tab and the taskbar still work, and quitting or a crash puts every window back.
