This is the safest way to keep session now, I like it.
But I think it can still be improved, session details can't be checked in delete window, but loading window can. This always confuses me cause I never name the sessions. So how about combine them(or more windows even all windows) into one window, and allow right click or menu to control everything. This will also make things simple : )
BTW it would be nice if the addon has a better icon.
