Let me start by saying I love Adobe software overall and your programmers are rock stars!
However, your "save as" function when working when creating/editing segments is confusing, and works differently than the long-established windows standard and the way 99% of programs work.
When you a "save as" button it means a dialog should pop up asking you to save the current segment under a new name. Right now, it just saves a new copy of the same unless you first change the title and then hit "save as."
Again, this is not the way "save as" works everywhere else in the universe, so it's unnecessarily confusing.
