This might be what I was looking for all along in a window manager. For the longest time, I've been dissatisfied with the drawbacks of both floating and tiling WMs, but hopefully this can deliver the best of both worlds.

This sounds really cool. The window "optimum size" they're talking about sounds a lot like what macOS does with its Zoom feature, where when you double click the titlebar of an app it resizes to the app's content size (as opposed to maximizing), which is something I'd really like to see on Linux.

If this is implemented I'll definitely try Gnome as daily driver for a while. :P

Sounds fascinating, can't wait to see it in action.

This is very interesting and innovative. I'm eager to see how it works in practice.
