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.

Breaks the YouTube subscription page. I tried disabling other YouTube-related extensions and uBlock Origin but it's still broken (never loads).

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

Так нужна группировка каналов, но реализация приложения ужасная.

UPD. Вкладка "Подписки" начинает жутко тормозить, лагает всё. Нагрузка на процессор на максимуме, вентиляторы включились на полную, комп чуть в космос не улетел от вашего "Рекоменуемого значка".

Great ideas but the performance hit, as others report, is too severe. Disabling other addons does not seem to help. (Firefox 133.0.3)

i actually like it but most features are locked behind a paywall.

Severe performance impact. This extension significantly reduced responsiveness of the YouTube subscriptions page. Channel group management page was very choppy. Actions taking at least 5 seconds to complete.
Update-disabling add-ons did not improve performance. I have over 700 subscriptions, maybe that is too many for the extension.
