After using it for a few days, it doesn't work anymore.
When you click on a subscription group, infinite loading occurs.
Turning off antivirus and uBlock still doesn't make things better.

Thank you very much!
I'm so glad to come back to normal.

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!!

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.

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

Good extention

good.
