Productivity Beats is in Alpha version.

User can do any changes in board without internet and while connection is available, offline data will automatically sync. After syncing site will reload to display the updated data.

We can reference a card while posting the comment using hash symbol (like #550 (550 being the card number)), this feature will not work when a card is referenced from a different board.

Currently admin or board owner can undo the board background image/color/pattern, but cannot remove it.

Some performance issues are in IE.
