I had a bunch of resources open, one of which I was in the middle of reading. I did "close all" in order to help a user figure something out. But then when I went to get back to my previous layout, I found that it wasn't there! The last autosaved layout was from yesterday when I closed the app.

Please also save an auto layout whenever the user does "close all" which is almost akin to closing the whole app down in terms of losing track of what you were in the middle of.
Thanks!
