emira, a tiling-scrolling WM for macOS: https://github.com/lightningboltemoji/emira

I know there are lots of options in this space, but I wanted to experiment with a new approach: a compositor overlay. During transitions (like scrolling on focus, moving a window, etc.) an overlay pops up and uses _screenshots_ of windows for animating while the real windows move below. Once in place, the cover dissolves out. It's not perfect, but this makes it _feel_ much closer to native.
