I've already answered that: sit on it, improve it.  We're not in
a hurry.

But... as you said it is big...  The indicator by itself is already
100 lines in total.  If dragging requires more than 50 lines extra...
then let's leave it.

Buttons?  There should be no buttons.  There is just the indicator
and possibly space above and/or below it.  The indicator should be
draggable, and the spaces clickable -- and when the indicator is at
the top or bottom and nano can still scroll further, clicking on the
indicator should scroll further in that direction.
