Saving tabs in window (rewriting the savefile)
My suggestion is to rewrite old saved browsersessions.
I have saved now the tabs in one window. When I add new tabs to this window I want to rewrite the old Savefile, but it is not possible. I need to create a new Savefile.
For example when I save tabs in the window and call the saved tabs "holiday". When I add tabs to this window I would like to rewrite the "holiday"-file, but it is not possible - so I need to create the file "holiday2" and have to delate the old "holiday"-file.
