I originally had the issue below, and it wasn't the filters. I just chalked it up to not every extension being perfect. I don't know if it was just a weird bug/something with another extension interfering, but it's now working good again, so 5 stars now

Original review
I like this addon, I'm someone who's subscribed to a lot of channels and this is a fantastic way to make groupings of channels I actually care about.

The main reason I'm giving it 3 stars is a bug I've been getting over the past few months which I only just now found out got fixed the moment I disabled this addon.

Basically, on any channel page, if I go to their videos page, the newest videos, like the newest 4-8 appear for a blink and then disappear. It's been quite frustrating, if this gets fixed I'll happily rate this a 5

This extension is very laggy and clunky to use. It's such a great feature that mildly pisses you off due to how slow it is to load anything. Not to mention the random days where I have to refresh youtube multiple times with multiple tricks to make the extension features actually show up. It's in dire need of heavy optimization work. Great idea limited by the execution.

laggy

decent even with the paywalls.

worst paywall is locking the sorting of community posts, and instead of just using chronological order, it shows the most recent posts from random channels. this is the only way to see community posts on a browser, by the way. in 'chronological order', but the 'chronological order' applies to the channels, so if you are subscribed to channels with a variety of activity, you get posts from months to years ago mixed in with daily ones. and the only sorting available without paying is how many posts from each channel you can see. its bad enough to make me want to refuse to pay you out of pure spite. i Just Want to see community posts in Chronological Order. at least give me alphabetization if youre forcing me into this 'see every channels posts' system so i can put the effort into finding them in a reasonable system. WHY would you put the channels in random order. its not useful for ANYTHING

anyway, as i was saying, the subscription grouping system is alright. the paywalls locks on it are more understandable, and its still usable even without paying. the kind of thing that would make me want to contribute if i could.

my subscibe menu is actuali destroy

would be five star if there was some kind automatic database of tags/groups that users could use at their discretion

[EDITED]

Hello! Giving it 5 stars. You deserve it! Thank you very much! Now I can set up size of thumbnails in the grid view. Thanks!!! =)

Most features are either locked or severely restricted behind a paywall. But they have updated the "play all" button to actually play all videos instead of just the latest 50, so it's good enough for me.

Sort your Youtube subscriptions into categories or tags, yes please! Export and import your subscriptions across accounts, yes please X2.

Easily see all the new videos from your subs by category, amazing! After ublock Origin, this is the 2nd best extension.

The filter "shorts/live" doesn't work. And shorts become more and more annoying. It would be awesome if this could be fixed.

EDIT: I disabled all other addons and the toggles "shorts/live" dont effect anything. Only "uploads" work but this effects all the videos. I tested this on firefox and chrome

I sent you the screenshots

Okay now it works in Chrome, but the thing is, I use this addon to not have to login on youtube/google.
Would be awesome if this feature could be added. Thanks for your support.

The extension is a good one, not complaining about that. My reason for rating is that the extension stores my data(my subscriptions) even after i logout of my YouTube account.(Like if my brother(or someone else) uses the same laptop/PC after i logged out of my YouTube account(or google account) he/she can still access my YouTube subscriptions by using this extension, isn't that a problem you must take care of as a developer?).
I hope that this extension can provide feature for different(multiple accounts on same device) accounts differently(i hope you get what i am trying to say).
Edit:I am changing the rating as i genuinely liked this extension, but i would install it again when i get the above mentioned feature.
