I would like there to be a way that after saving or closing a session, Finale would NOT delete the undo history.

I also would like the undo history to be more descriptive in what the action was.  For example, instead of saying "simply entry edit," it could say "1/8 note rest entry" or something like that..

Lastly, If I would like to undo an action from several steps before, I would like Finale to NOT undo all actions following that one.. and instead, it just undo that single action.  For example, let's say I deleted a measure, then I did many other actions after that, such as simple note entries, expression marking entry, repeat signs, etc.  and then, I realize that I would like to undelete that measure from several steps before.  If I go to find that that action (undo delete measure) in the undo history and undo it, it will also undo all the following actions (simple note entry, expression entry, repeat sign entry, etc).  I would like it to undo only that one action, but leave all the following actions the same.
