I love being able to close Aqua Data Studio and reopening it and having all my tabs that I had open returned. This is great if I have a windows update mid day or something like that where I can close out reboot and start back where I left off. I would like this same thing but being able to save the session with all those tabs and name the session. This was if I am working on something and high priority issue comes up where it will require multiple tabs to organize, instead of mixing tabs up I can save my session on where I am at and close it to open a new session and start opening multiple tabs again until I need to return to the prior thing I was working on.
Notepad++ has a similar plugin called session manager.
