so, i have tried to use engrave mode to resize staves, and such things. what i am currently doing is resizing the first measure of a piece, which i put alone on the first system, so that it is not awkwardly stretched the width of the page. however, i cannot move the handles with the cursor, i can only move them with alt-arrow. this is ludicrously slow, and it took at least a minute of holding down the button to resize this one element.
is there a way to adjust with the cursor, or something i am missing?
otherwise, consider this a feature request.
