Scrollable keys view

[flit]

From user Jon by email:

I just started using MidiKeys with Zoom lessons, to share my screen and show keyboard parts to students and band members. It's a really nice tool for this feature.

The only challenge is when I grow the window, there is no ability to scroll the visible range of the keyboard.

Might it be possible to add that in a subsequent version?

I'd REALLY appreciate it!!
