Set maximized window property (send to background)?

Hi, I’m new here and looking for help with polonium - new tiling window manager. By default it sets window to the foreground when it’s maximized. I’m trying to set it to background by default. Does anyone know how this could be setup?

I’m trying to get it to work in window rules, but can’t quite figure out the workflow.

I think this is better asked on their GitHub, since that’s a 3rd party add-on :slight_smile:
