I'm sure this has been asked in various ways (I've seen hints in my searches before posting), but I'm not seeing an explicit question or answer so far that addresses this.
I want DO to automatically remember my open tabs when the last lister is closed (whether or not DO itself exits), and then automatically restore them when a new, first lister is opened. This would be akin to a web browser re-opening the tabs you had opened the when the last browser window was closed.
I know about the "Default Lister", but that seems to store a static set of tabs, which has nothing to do with what I was doing when I closed the last DO lister.
