A few question about KDE Connect

I just started using KDE Connect to be able to control my Media PC i use within my living room by via my Android Phone.

However two questions came up that i wasn’t able to solve yet.

  1. Is it possible to somewhat set “default” settings/rules for new devices i want to pair? For example by default Smartphones are able to control the Mouse Input which i don’t want to be the default for new phones (usually i just want them to be able to share links)

  2. Does KDE Connect really need to run on the background of my Phone all the time (even if not used)? And is there a way to close the app after using it without the need of paring it again later?
