I would like the ability to navigate to the previous document I was editing quickly/easily. E.g. a "Back" button would let me navigate back to the Assembly document I was just editing.
Use Case: I'm working on an assembly and I notice an interference. I open the offending part from inside the assembly, edit the part, then save the part. I don't want to close the part- just navigate quickly back to the assembly. Currently, I have to look through all the open documents to find the assembly then activate it. If there was a "Back" button, I would click it (or assign a shortcut key to it) and navigate back to that.
