So far, this add-on has worked well and does what it's supposed to. There are a couple of issues with it though:

1. It slows down YouTube/causes YouTube to not work properly - I have noticed that when this add-on is running it takes much longer for YouTube search results to load (like a noticeable wait and I only have 2 channels blocked). The same kind of delay happens when loading an individual channel. It's certainly not something that would stop be from using this add-on, but definitely something that could be worked on.

2. I have to disable this add-on to see my YouTube notifications! - This is definitely a pain in the arse and needs to be fixed. If this add-on is enabled and I click the bell to see my notifications, it is completely blank. Once I disable this add-on, I am able to see my notifications just fine.

Other than that, thank you to the creator for providing such a much needed add-on!
