Thanks for the message…. we do have Undo/Redo as you mention in the desktop version. We actually have it in the Cloud AI version as well but have it hidden at this point. We will release in Q1 on the Cloud as well….. long story.
Your other note: that would be a good idea to have the memory of the last project opened. It has never come up so would not be immediate on our list but it is a great thought for efficiency. In particular, if you have many projects.
