Recommending a consolidated Add Measure dialog
Why not consolidate the four "add" measures options (Insert one, Insert measures, Append one, Append measures) into a single multi-purpose dialog?
A generalized Add Measure dialog (like the one show below) could conveniently handle most situations:
• adding or appending a single measure is a menu choice
• adding or appending multiple measures leads to a dialog anyway, and if accessed by a single keystroke that frees up keystrokes currently dedicated to the task.
