Can we please go back to the UNDO we had 2 years ago? There may have been some slight problems then but nothing compared to what it is today. There are steps missing so it is not a true undo; if you try to go back we crash. If we cancel, we crash; and if we go look in the past undo and then try to back to a more recent place we crash, etc. Isn't it a normal procedure to go back to a system that worked better instead of trying to patch up what we have today?
