As of the recent update, the extension no longer seems to be working. There are still groups but no ability to filter by group at the top of the subscription feed. Is there a limit on how many channels it can handle?

Edit (reply to developer): I tried disabling all other extensions (in LibreWolf), but it still doesn’t show the group filters at the top of my subscription feed. I get the same result in Firefox. I’m not sure what would be causing a conflict, as I haven’t recently changed anything about my browser configuration.

Edit (reply to developer): I wasn’t hiding the groups, but I did notice that the groups had disappeared. So I restored from my Chrome settings, and it seems to be working now.

Makes YouTube usable, frequently adds new features. Bravo

Once you get used to navigating all the options, it is very convenient. The developer responds quickly. I had a problem on the main subscription page. Filters at the top of the main subscription page may have issues that are limited how YouTube provides data(slow load or repainting) when filtering on channels/groups that don't have many recent videos. The workaround for me was to leave the upper filter set to "All" (under "Show Filter" icon) and use the PocketTube left nav to filter by group/channel. If possible, I would suggest PocketTube display a warning instead of continuing to attempt to load videos.

Great add on! Love being able to quickly access groups of channels and their videos.
