Users who want to study small subsections at one time (eg, "lesson 14") are currently best served by creating lots of little decks. This is because: - selective study is a bit cumbersome to switch between - the graphs and statitics are for the entire deck - selective study can be slow on mobile devices - when the list of cards to hide/show is big, or when there are many due cards, performance can suffer - scheduling can only be configured per deck Groups are intended to address the above problems. All cards start off in the same group, but they can have their group changed. Unlike tags, cards can only be a member of a single group at once time. This allows us to divide the deck up into a non-overlapping set of cards, which will make things like showing due counts for a single category considerably cheaper. The user interface might want to show something like a deck browser for decks that have more than one group, showing due counts and allowing people to study each group individually, or to study all at once. Instead of storing the scheduling config in the deck or the model, we move the scheduling into a separate config table, and link that to the groups table. That way a user can have multiple groups that all share the same scheduling information if they want. And deletion tracking is now in a single table.
