I think it should be more clear what the options do

Everyone works great, except mixes are no longer hidden.

Works great! I don't know if this would be possible to implement or if I should download a different extension for this (if so, please reply to this and tell me), but an option to hide the breaking news tab would be nice!

Not blocking mixes

This addon is a lifechanger. No more nonsense "recommended" in the search feature.

Only thing is that this is slow as hell on occasion. Takes a long time to search something after a while.

Neat little extension, the search results are much better without the recommended nonsense nobody asked for.
However, two things that could be improved crossed my mind:
1. The 'hide playlist' option. When hiding playlists is on and you filter for playlists, the extension enters an infinite loop. Would it be possible to make an if statement to check the applied filters?
2. Search in playlists function. Say I have a playlist open and want to search for a specific video within the playlist, would that be possible to make? Ctrl+F is limited to what is currently loaded on the page...

Give an option to disabled bold channel names.
