Editing SUPER FAVORITES items

When I open my SF there’s tons of addons in it. My goal is to only have the favorites I save there appear. Late last night I attempted to remove 2 of the addons from the SF folder and i think it actually deleted the add-ons.

1. Is this true?

2. Is there a faster way to delete multiples SF items instead of one at a time?

3. By what I’ve described, if I simply uninstall SF addon then reinstall it, will the SF being totally empty now?
