- `alphabetical` - Rooms are ordered alphabetically by room name. This is the default.
- `size` - Rooms are ordered by the number of members. Largest to smallest.

- `joined_members` - Rooms are ordered by the number of members. Largest to smallest.
- `joined_local_members` - Rooms are ordered by the number of local members. Largest to smallest.
- `version` - Rooms are ordered by room version. Largest to smallest.
- `creator` - Rooms are ordered alphabetically by creator of the room.
- `encryption` - Rooms are ordered alphabetically by the end-to-end encryption algorithm.
- `federatable` - Rooms are ordered by whether the room is federatable.
- `public` - Rooms are ordered by visibility in room list.
- `join_rules` - Rooms are ordered alphabetically by join rules of the room.
- `guest_access` - Rooms are ordered alphabetically by guest access option of the room.
- `history_visibility` - Rooms are ordered alphabetically by visibility of history of the room.
- `state_events` - Rooms are ordered by number of state events. Largest to smallest.
* `dir` - Direction of room order. Either `f` for forwards or `b` for backwards. Setting
