Today's update (5b56347) brings with it the following changes:
- Back button was added in the message reading pane, so that user can go back to their corresponding location.
- Improved accessibility in object/container button bar.
- A lot of the database queries have been refactored, which should make them more robust. There is also a slightly higher risk of regressions.
- Active tab selection in message reading pane has better usability.
- New message link in message reading pane can now be clicked.
- Removed unwanted "Unread" button from outbox message reading.
