The CTRL+Z (Undo) should have more steps.

As we us Ctrl+Z for other program we can go quite back but in case of LabVIEW we are usually limited for 4 to 5 steps only. I think there must be some option to go back more step because some times in block diagram it happen which bother a lot specially if your not in good mood 🙂

LV 2009 raised the limit from 8 to 30. You can raise it as high as 99. Various people argued that the default should be 99, but we still have users that work on low-memory machines for whom the higher limit would be a problem -- most edits don't require huge amounts of undo information, but some do, particularly some "make current value default" operations on large arrays. 30 was the compromise.

Functionality already in LabVIEW. NI LabVIEW 2010 changed default number of steps to 99.
