Sorry you had to struggle through this. I'm trying to understand where the confusion came from and whether the actions of extension can be described better. Was it because there were two existing FF sessions with 4 tabs each and Session Boss captured both of them and showing total 8 tabs? Was the save button's tooltip on the "Save all windows and tabs" not clear enough? May be re-worded to "Capture all tabs in all windows"? Also there's another button next to it for capturing just the tabs of the current window. May be its tooltip should be re-worded to "Capture just the tabs of the current window"?

There're some form of editing on user sessions now. You can delete windows one by one from a captured user session now; also the tabs in a window can be deleted as well. More session editing will be added in the future. Auto backup sessions cannot be modified since they are a snapshot of history; they will be auto-cleaned up when the last period expired. They can be copied to a user session to be edited.
