If the content of a SQL commander gets changed, the commander tab gets a "dirty"/"changed" mark in the tab name. This if fine. However, if one undoes the changes the mark to the last saved state does not get removed. It would simplify working if it was unmarked, because in such case one would easily be able to undo until the last saved state. Maybe it is just because I am not used to using reload from disk. On the other hand, one needed to confirm then that one really wants to discard the changes. To me, pushing ctrl-z is just more convenient.
Thanks for the suggestion. I will add your vote for this improvement request
