Tiling a Fullscreen Window - Feature Request

[HideyoshiNakazone]

I would very much want to have the ability to tile a window that is in fullscreen (such as a youtube video), so i could have that video in fullscreen but occupying one quarter of the screen. Does this feature exists? Or would it be possible to implement?

maybe some implementation ideas could be taken from xmonad: https://xmonad.github.io/xmonad-docs/xmonad-contrib-0.16.999/XMonad-Util-Hacks.html#g:1

(and hopefully the still-relevant feature requests on this issue tracker are ported over to pop-os's upcoming COSMIC DE!)
