Maybe they fixed it, but a while ago the whole update process broke because of a bad Open Office package. I'll switch to Android / Kali Linux (which wasn't supported in the beginning) soon.

Depends on the window manager/desktop environment you’re using, but there’s dozens of Gnome3 extensions that do exactly this. “Caffeine”, for example.
