Valid, but I’m unsure if mouse use needs to be mutually exclusive with a tiling window manager, and would like to suggest that all tiling managers are not necessarily made equal.

Niri for example, tiles but additionally introduces an infinite horizontal space, where you can slide between different windows like they’re on a film strip. The slide into view works with a mouse, and you can easily setup mouse bindings to move and reset windows. I think it’s better than just a stock floating windows manager because it feels easier for me to navigate an infinitely wide left-right and up-down space as opposed to an infinitely deep space into and out of the screen.

vimium is my solution to the web.
