I feel a bit bad for @Neicudi because there are tons of things to do already, but it’s good to bring in the ideas before someone has to actually vote on it
The idea: Just showing the review cards as lessons is already OK, and it is good that cards can be styled differently during lessons. But I think it would be great to have cards that only appear during lessons for something like chapter names, general explanation, start of a new category of items, etc. That only makes sense with indexed decks obviously
So you have a type of card that only has a front, maybe doesn’t count as a lesson, and appears together with the next item, and no reviews.
