While using the Note Mover tool I would like to have the ability to select the region that the "Replace All" function affects.
Imagine being able to select the note mover tool, choose the note or notes you wish to have changed, go to search and replace, choose how you want the selected notes to be affected, and then be able to select an 8 measure region and apply the "Replace All" function and have it only affect the notes in the selected measures while the notes on either side of the selected region remain untouched.
. . .
You could even expand that capability to the "Find" function. So for example find all A-flats in this 16 measure selected region. This would actually be very similar to another post I've seen on here titled "Search for Character/Note"
