clock supports pango markup.

network and battery don’t, but I really want to use <b> on network for formatting like <b>IP:</b> {ipaddr}.

I haven’t confirmed with any others.

Go through TODOs in wayvnc and neatvnc that cause abort() or exit and make sure that they have error messages attached to them.

Currently number values for config can be only specified with exact pixels number. Would be handy to support percent values as well. For now it's fine to implement it for width & height

Some apps don't want to scale properly. Apps known not to scale:

rofi
alacritty

If anyone finds other apps that doesn't scale, comment and i will update the list. For the moment i will not work on this because i feel that isn't strictly needed right now but if someone can look at the codebase and find a solution feel free to make a PR
