I saw comments/reviews mentioning "right-clicking the tab doesn't offer the option to rename a window"

I was also confused initially, but I realized that you need to right-click "Window 1" bar in the add-on's drop-down, not the window itself.

My main desire would be allowing me to minimize the windows' lists so I can navigate them in the add-on quicker instead of having to scroll past all the tabs to get to the window I want to rename/manage. There already seems to be an issue on the github repo requesting the ability to fold the lists, but other than that it's a simple little tool I already appreciate.
