Unfortunately no more checkboxes at the moment. Power button is missing. "Selection from to" not possible at the moment. From the usual five stars, unfortunately only 2 stars.

Now the extension is working again.

Unfortunately, it has been no longer possible to select something in the subscription box (when grid view is selected) for a few days now (list view, however, works), since YouTube tinkered with its website (again).
