I often have up to ten or more workflows open at a time, several are named and are active workflows that I want to save, and the rest are just scratch workflows where I'm trying something out. When I close Alteryx it asks if I want to save changes to workflows, with the list of all the workflows. If I don't want to save the scratch workflows, I have to cancel, close each one individually, then exit Alteryx again, saving the ones I want to save.
It would be great if there was a check box next to the workflows in the list where you could check the ones you want to save, and it would drop the rest.
