Feature/UI suggestions

🖖 Hi KDevs : )
overall I'm very thankful for kdeconnect, especially because of the clipboard sharing plugin. But following are some missing features I experienced when using it.

important:
· full remote control of peered android device
· support for full notification android.text 

nice-to-have:
· informative & aesthetic popup overlay from systray (basically duplicating the window view, but activated by hovering instead of clicking)
· plugin to allow to fetch files from host PC
· roaming support

Just wanted to share these with you.
