I've tried many related add-ons & this is my final choice, especially for easier accessibility. I also rely a lot on visuals due to bad eyesight which causes fatigue.

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.

It works for me perfect

Interesting concept, also adopted by other tab managers (creates lists of tabs, which are much easier than tiny squeezed tabs in the built-in bar to view and handle). The preview of the tab is very useful, outstanding from other tab managers. On the down side, the save-all-tabs function does just that, saves all tabs... And nothing more. No management of saved tabs, controlled restoration, moving tabs, nothing at all. When restoring the tabs, it simply throws them all open at once, which can be disastrous if there are hundreds of tabs (even more so if the tabs are from authenticated sites, which may not like multiple tab access.) Last, but not least, restored tabs ignore containers.

Beautiful and nicely addons!!
Just one point is it super heavy for my old laptop...
