Expand & Contract Taskbar for "Drive Space" plug-in

Plug-in "Drive Space" (in the end-user's example: located on the left of the Taskbar): When a drive becomes available or unavailable, the "loaded program field area" in the taskbar remains unchanged. In other words, there can be significant 'whitespace'/blank area which is unused as the drive space zone is not recalculated (expanded or contracted) and updated. Would be nice if the number of "columns" or "drives" maximum could be specified so as to limit complete usage of the "loaded program field area" if too many drives were loaded in an expanded/contracted (dynamic) capability.
