You asked about feedback on the new minimap rectangle hiding in the thread about build 3014.
I think the new hiding behaviour makes the minimap even less useful than it already is.
The minimap rectangle is more useful than a scroll bar thumb because it shows exactly which part of the buffer
is visible on the screen at any time. It does look odd though, because it will always be at same vertical position
as the scroll bar thumb (for long files).
Hiding the rectangle resolves this visual oddness, but makes it harder to locate the current position in the minimap.
IMHO, it would be better to just use the minimap (with rectangle) as a scroll bar and disable the actual scroll bar entirely.
