Views for all selections [with vertical scrolling] have been implemented, where enough items come after the current selection to fill all lines available for menu items. The other parts remains a ToDo for now
The new loop method allows for more advanced usages (e.g. when you want to use the cpu core for more than just the stupid while True, listen for btn presses procedure but also invoke other commands from time to time - then you can implement your 'own' run procedure!)
