Yabai: Feature request: Ability to set default initial window behavior

[lauritk]

I was wondering if it's possible to config initial default window behavior so that new opened windows are for example floating windows (or what user prefers). It is sometimes annoying when new windows rearrange my view and this option would be helpful.

What you're looking for is called window rules.

docs tl;dr

```sh

float all Safari windows by default

yabai -m rule --add app='^Safari$' manage=off

float all windows by default whose title ends in ' Preferences'

yabai -m rule --add title=' Preferences$' manage=off

Make Chrome Picture in Picture mode windows appear topmost and on all spaces

yabai -m rule --add app='^Google Chrome$' title='^Picture in Picture$' manage=off topmost=on sticky=on

Thank you, this was it! :)
