I think I saw this feature before, but cant find it now. How can you select multiple lists to study at once? I don't really use the adding function, and ive never used 'study all lists'. I just wanna choose a few of the lists I've made to study at once.
(Also, if anyone knows how to put pre-existing lists into a 'big list' grouping, that'd be cool too. I know I didn't explain that well...)
