Could you build this?

Partial The settings UI and app shell are easy to build, but controlling macOS Spaces and window placement relies on private window-server APIs and undocumented behavior that AI assistance can't reliably produce.

What it would actually take: A real version needs a native Swift/AppKit app that hooks into macOS Spaces, probably through private CoreGraphics (CGS) APIs and accessibility APIs, plus a global hotkey and window-capture layer. Getting it to work across macOS releases requires reverse engineering the window server behavior and maintaining it as Apple changes internals.
