Mostly, it's kinda hard to manage a huge amount of groups and tabs, as you can't multi-select groups and tabs. It's really hard to move tabs around groups, organize the order of groups, delete multiple groups at once, etc. It's not as practical as it should be. And I think the UI is kinda outdated, though that's just aesthetics. But also, it is the only tab group extension I've seen that saves this much memory. You open a group and it doesn't load 60 tabs unless you specifically tell it to. For that alone, I don't switch from Firefox to Chrome (because Firefox mobile fucking sucks, at least on MIUI). I also like the praticality of deleting tabs from a group. You open the group and close the tab normally, it counts. For some reason other extensions are more convoluted than that, which is fucking nuts. And lastly, the backups are hit or miss. The automatic and manual local backups are great, but the bookmarks are really weird to me. Like, why doesn't it synchronize with current tabs (or at least have an option for that)? Instead, it adds the initial tabs and then keeps adding new ones infinitely. It's looks like a mess and I see no point in it. For me to get all my groups, as they currently are, as bookmarks, I have to delete the STG folder and wait for it to save again. That or I'd have to add every single one manually, but that's not viable.

I'd give it a 3 for lack of practicality when organizing shit, but it keeping me stuck on Firefox because of how useful it is makes it a 4.
