nice one!

This should be ready for review; however, betterFolders is a big issue.

While this fixes all issues with better folders on both treatments of the experiments, the patches are a mess, and some of them might be able to be removed/optimized

Not familiar with the dev process of Vencord, is there a way for me to somewhat easily test these changes?
(Since this fix is essential for me I would be glad to help test it)

Not really what I was looking for, but it is fine.

Anyway, just tested and it works as expected on my machine.
