Could you build this?

Partial The UI is straightforward, but a polished Cmd-Tab replacement needs native macOS work on Accessibility and window/Spaces APIs, some of which are private and fragile across OS releases.

What it would actually take: Build a native Swift/AppKit app that uses the Accessibility API and CGWindow/CGS calls to enumerate windows, Spaces, and displays, and it needs a global hotkey and a custom switcher overlay. The hard parts are reliable per-Space and multi-display window handling, which depends on undocumented APIs that can break with macOS updates. Open-source projects such as AltTab show the approach, so a solo developer with some macOS systems experience can finish it.
