RFE: ui change: disable line overview section in main window

The UI on a phone is not optimal for a small phone display.

By en/disabling the lower line section on the main display we gain a lot a space. Also the "details" section can be smaller.

This would give the ui space for bigger buttons on the toolbar.
Also the Buttons on Profiles and "Number"  could be way bigger and in 2 lines each.
