Paywalled.
I should have read the other reviews before trying it, I guess.
I understand that you want money for it, but then put it in the first line of the description.
Most people don't want to pay for an extension, so you are just creating suffering.

Paywalled options in a extensions should not be a thing, specially if it is one of your main options.

Haha, started this up and is has lots of nice features, click any feature and it says "only for patrons".

Nice.

The features you'd want the most are blocked behind a paywall, so this is useless.

someone sent this to me and i found out later that the only feature worth having is paywalled, i originally was just going to leave it at that and uninstall, but the dev was being cringe in response to other reviews.

Literally wanted this for one thing, to organize my watch later playlist by video length, and they paywalled it. With no mention on the download page that you need to pay. This is literally the first add-on I've ever been told I needed to pay for to use a feature. Really Scummy.

Playlist filtering (the only reason I got this addon) is paywalled... Tip to dev: Maybe indicate clearly on the addon page which features are paywalled to avoid user disappointment and low reviews.

requires a monthly payed subscription. rediculous!

Wow, nice paywall app, first time I've seen that...You know, lots of other addon makers spend time updating their apps too and they don't beg for money. Greeeedy.

Popup his ads on YT.

Edit: Not true ? Then what's the popup lead to the ads on Youtube of your other addon ? A joke ?
Stop lying.

slows down youtube overall

slows down youtube by a lot and moving videos between playlists is a patreon exclusive.

All i want is to sort by upload date. This advertised it could, but there is no option to.

Moving several videos at once from one playlist to another is paywalled (prompt for Patreon subscription). Lame.

A trial period, or a limit on the number of selected videos would have been better. And make that clear on the add-on description. Otherwise it just upsets people.

I understand it takes some work to maintain that, but give something useful to people first. No one cares about groups.

EDIT to answer the developer: Such nonsense! If so many users care about groups, why don't you make that only a premium feature? I would have gladly paid for this if it had been made in a way that made more sense and not so overtly money grabbing. You just wasted my time.

EDIT 2: Sir, I do appreciate your work: it's a great idea, you made it work, and you keep maintaining it. Bravo. I'm a developer myself, so I know it takes time, skill, and dedication. My point, like most bad reviews you got, is that most features are paywalled. And that's not mentioned in the plugin description at all. It's very misleading, and it's done on purpose. We installed the add-on expecting all those features would be free. That was our EXPECTATION. Discovering we have to pay, we felt tricked.

Please just be clear in the add-on description about which features are free, and which are premium. That's all. No one is arguing with you that your work deserves to be paid. We are upset just because we felt tricked. That's not good business practice. I'm taking the time to write that so you can do better in the future. Best of luck to you. Don't hate me too much :)

Pop-up ads, clicking on them results in receiving "reminder" emails to your email. Not a good practice.

Edit: A pop-up ad is still a pop-up ad. Also I didn't give permission to be solicited through my email. Nor give my email handle at any point. How your add-on manage to get a hold of it is a complete breech of trust.
