@leocg Really? I tend to have multiple windows with upwards of 10-20 tabs open in each while working on multiple projects, including research or cross-checking tabs. When I close out, I don't want to be deleting every single extra tab, in order to retain the Island Tab groupings of my original session. Limiting it to this 'Where you Left Off", rather than (also) for "Open a Specific Set of Tabs" setting makes this actually quite tedious.
