I notice Xubuntu can let me change the opacity of inactive windows, which seems nice for having small videos playing while showing my terminal below. But it quickly gets annoying when doing anything else – I don't want every inactive window transparent, and I'd rather not go into settings all the time to turn it off. Can I just set it for one window?
(Bonus points for turning it into a script that can both set transparancy, always-on-top, and remove window decorations)
