The problem
Alt-tab and multiple monitors are how we've juggled windows for 30 years. I wanted something spatial: zoom out, see every window at once; zoom into one, work in it for real; zoom back out. Like a map for your desktop.
On Linux there's niri and driftwm (they're compositors). On Windows you can't replace the compositor — so the question was: can you do this on top of Windows, with the real windows, in a single exe?
Attempt 1 (and why it fails)
The naive idea: capture every window, hide the originals off-screen, and draw the captures on a fullscreen surface. When the user "dives" into one, show the real window again.
