  - Exposes high-level objects like `Rooms`, `RoomState`, `RoomMembers` and `Users`
    which can be listened to for things like name changes, new messages, membership
    changes, presence changes, and more.
+ - Handle "local echo" of messages sent using the SDK. This means that messages
+   that have just been sent will appear in the timeline as 'sending', until it
+   completes. This is beneficial because it prevents there being a gap between
+   hitting the send button and having the "remote echo" arrive.
 
 Later versions of the SDK will:
  - Automatically retry requests to send messages due to network errors.
  - Automatically retry requests to send messages due to rate limiting errors.
  - Mark events' sent status (e.g. 'not sent').
- - Handle "local echo" of messages sent.
  - Handle queueing of messages.
  - Handle pagination.
  - Expose a `RoomSummary` which would be suitable for a recents page.
