couple more I consider pretty big:
--Project name in the titlebar
It currently puts the name of the event sheet in the window titlebar, but it needs the project name too. I sometimes have a few projects open, and it would make telling them apart much easier.
--Search; jump to selected
I know you suggested above to scroll back to the event you were on before you searched, but I would prefer it jumped to the currently selected event in the results. If you don't select a result, then jump back to where you were. (isn't that really what you do after you search?)
oh and a bit late, but you can cut and paste global variables, the deleted events are put back if you paste immediately. Just ignore the warning. (you can move them to their own event sheet, since they are global, the event sheet doesn't have to be associated with anything.)
