2.X versions worked great. 3.0 update introduced hellish lag and constant crashes. It's had 13 version updates/patches in the past week and still has horrible lag and crashes. That should tell you all you need to know.

Update, since the dev 'responded': rolling out an update that was a complete rewrite, with no warning or notification provided - one day the plugin worked, the next day it simply didn't - was a terrible idea. A mistake, even. One that was fixable by reverting back to known-working code. Instead, the dev decided to push forward and insist it worked fine and then try and patch it over and over and over again, claiming to make progress (and yet lag time is still just as excessive as it was at the start, 13 updates later, dark theme is broken, runaway RAM usage and crashing is more rampant than ever, etc).

Trying to blame these failures on a lack of testers, rather than a lack of wisdom to admit a mistake and rollback to a working version until testing can actually be completed, says far more about the developer than they'd like to admit, apparently. Suggesting users hop in the discord to help with features is not ideal, especially since the developer isn't even the admin of their own discord, and the actual admin members are shitheads that prefer to troll people and exhibit constant toxic behavior rather than actually provide help or support, which is genuinely insane.

But hey, at least the 2.x version works exceedingly well. Instant, responsive, snappy, full-featured, and above all else: it's never crashed my browser. If you're looking for a plugin that'll work great, install the 2.x version, that one deserves five stars. Or go use the competitor I guess, since that's literally what the developer is suggesting.
