Also, though it keeps centered on the top (verticall scroll keeps being reset, 
need to figure out how to solve that)

Option added, though not functional. Needs some real thinking how to make it 
work smoothly :-)

You can't switch yet at runtime, so you have to edit 
src/songcanvas/Cursors.cpp, PlayCursor constructor, lines 40 - 41.

What about, hmmm,  [ SPACEBAR ] + scroll wheel to switch mode ?
[ SPACEBAR ] is also used to place the playhead cursor to a new position 
(seek), not sure if it will be confusing. Anyone with a better idea ?

Of course, once the Song information display is back, there will be a 
buton/something else that shows what mode is active, and one can select from 
there too ;-)
