During development of sequences I often do "trivial" changes in order to check parts of the sequence that I do not want to save afterwards (e.g set Run Modes of steps to Skip). It would be very helpful to see the last changes that can be undone before clicking the Undo-Button arrow (the same applies for the Redo Button of course). This feature would have two major advantages, since one could...
- ... decide whether it makes sense to save the last changes or whether those were only for trial reasons and hence should be neglected
- ... undo several changes in one step
This is implemeted in Microsoft Office programs for example (see screenshot from MS Excel) and I use it there pretty often.
