I’m running Ubuntu Gnome.

You should try Sublime Text then.

Hey! Thank you for featuring me!

Holding down the power button hard restarts the phone. It is not advisable to do that unless absolutely necessary, such as when the phone hangs and becomes unusable. Think of it as pulling the plug on your PC vs. shutting it down normally, the processes running in the background don’t have a chance to shut down…

CF.lumen changes the colour for the whole screen, even the navbar; and one of the modes it uses directly renders the screen via hardware which makes it less taxing on the phone, as opposed to screen overlays.
