PERFECT. It is an amazing app with useful features. 10/10

Love this. Thank you.
A small wish? After I've viewed a vid, it can be filter out in the Subscriptions feed, that is good. Can also that vid "loose" its blue dot on the channel under Subscription Groups and my custom groups? Because now I view random vids in my subscription feed, and if I have time I dive deeper into my Groups to update my self on the channels to catch up on vids I missed in the feed. But very often I find that I've seen the latest vids on channels, but the channels are still "tagged".

And the Deck function on Firefox are only loading (spinning) when I open the deck. In Chrome it works correctly. Thank you.
Edit: Last version 11.0.4 has corrected this! Thank you!! 5/5 stars :)

My wish-list:
1. Store custom group images locally, not on Imgur
2. Delete Imgur image after sub group deleted
3. I have no clue where you store the group playlist(50 videos). The playlist is "Unlisted" and the owner is not me. You can create 100+ videos playlist on my account and set it to private, why not do the same thing when creating 50 videos playlist?

This add-on is 5/5 useful and easy to use.
But...
Privacy 1/5

Edit to 5 star because dev answered my question.

I actually have a reason to check the subscriptions page. Previously, it was a giant mess. Now, I can organise everything into their own category. This is something YouTube should seriously consider adding.

Awesome YT extension that helps me categorize my extensions and view videos from my subs only when I want to on my Subscriptions tab. Essential for me because I can hide videos from my sports subs when I can't watch a sporting event live and want to avoid spoilers from new videos.

Outstanding add-on if you use YouTube a lot like I do. Well worth the subscription for Pro version too!

Случайно узнал о данном расширении и мне оно очень нравится. Надеюсь и в дальнейшем оно продолжит развиваться

It works as advertised. It does organizes my playlists very well

add-on absolument indispensable, à quand une traduction en Français ?
absolutely essential add-on, when will a French translation be available?
