I really like this add-on and its extra features like setting an icon for the groups!!
...just one thing, maybe it's unrelated but it started to happen right after I installed this add-on:
- On YouTube's home page, when marking their recommended videos to "not interested/don't recommend channel", randomly they just pop back to normal and I have to set them so again!! Very annoying!! Could you fix this please?

*** I can't screen grab it because it happens randomly but MANY times!!
Try to mark ""not interested" a full row of recommended videos, scroll down and they will pop back to normal!!

The `watched` status is not handled properly, and in two ways.

On the subscriptions page, it seems like the Hide Watched checkbox needs to be re-applied for the filter to work, the Play All button here does not work.

In a Channel Group page, the Watched tab doesn't remove watched videos from the list.

Very useful extension.

And personal opinion ----

On the subscription page.

If only want to see one group at a time.
When switching from one group to another.
On/Off button operation is very troublesome

The group at the top directly switches to single-select mode or multi-select mode.
Instead of giving each grouping to a On/Off button.
That would be better.

In this way (on single-select mode), when switching a single group, only one click is required to complete the operation.

forgive my poor English & thx for ur job.

Header in subscription list (that permits to turn on and off each category) works in Chrome, not in Firefox...

This extension makes keeping your YouTube subscriptions organized and much more convenient to access!

I can't make it work, i watched the tutorial and everything but the row at the left doesn't even show.

The addon doesn't work unless i disable all my other addons

Good extention

Please optimize this extension for Firefox Android
