[Feature] Automatically launch the first or preferred app after timeout

[0Raik]

Adding a countdown then automatically open a preferred app. I use a media PC with KDE Connect as my remote so having an automatic launch will save the user switching from one app to another in the phone.

Thank you for your valued time and effort in making such a wonderful, pretty and useful app. A must have with lots of room from improvement. Thanks again for the love and care and have a great day!
