KDE Connect is awesome!
One of the most useful features is a functional replacement to “click to call” on Web sites. With KDE Connect, when you connect your Android device to your desktop, you can send a phone number on a Web site and instantly tap to call.
Google Chrome will do a similar thing, but you have to be running Chrome on both devices.
Phone notifications will display on the desktop as well. One thing I’ve noticed is the desktop notifications for an in-bound call don’t time out, but stick around.
Might be a bug, will have to ask Nate :-).
