It would be nice if lessons could auto-adapt to hibernating cards. I’ll try to explain what I mean by that:
When I start my daily batch of lessons, there are always some cards coming up that I immediately hibernate because I already know the items fairly well. That leads to me getting less lessons in that batch - since the hibernated items are removed but not replaced - and having to go back to lessons several times to reach my desired daily number of lessons.
The ideal solution would be to immediately replace a hibernated card with a new one while in lessons mode, to keep the batch size as intended.
