The idea is great, but the actual functioning is poor because it breaks some behaviors in YouTube and I had to uninstall this extension because of it.

1. When doing a search, the results page sometimes gets stuck refreshing the results, basically the results are caught in a loop of refreshing over and over so you can't click on anything.

2. When scrolling videos, YouTube uses lazy loading, but with this extension enabled, the videos do not load and it's just blank, therefore video results beyond the page break fail to load.

3. There are glitches when loading your main subscription feed page, things like shorts showing up then disappearing, despite what option you have selected. In my usage, I have shorts disabled, however they continue to show up sometimes on page loads.

4. The actual loading time of pages on YouTube is noticeably slower, this is most likely due to this extension using additional resources and causing it to lag.

5. Not the extensions fault but a byproduct is this will make your YouTube mobile app experience worse because your subscriptions are now all together, so if you use this extension to subscribe and be able to organize them where you wouldn't otherwise subscribe, then your lists are useless on mobile.

6. I don't appreciate the advertising for your extension upgrades. Yes, we understand you'd like to make revenue but let users show/hide these options and once they make their choice do not advertise this again. IF users want to upgrade, they can do so later on their own terms.

Again, it's a good idea but hopefully YouTube will adopt collections natively (as they have done beta testing with select users) and this will then be able to be used on your account across all platforms and devices.

The main feature I use is the subscription categories and the ability to hide shorts, once YouTube adopts this it will be great. Hopefully this extension will inspire YouTube to release collections to all users and feed options such as hiding shorts.
