Asana Goodies adds a few tweaks to Asana (www.asana.com) web UI:
1. Inline image display. Images are displayed right on the task pane - there's no need to open them in a separate window.
2. Subtask summary. Subtask summary added three indicators:
(a) subtasks icon if there are any subtasks inside a task
(b) initials of all assignees who have active subtasks
(c) the number of subtasks create but unassigned (sometimes we plan for the stuff but forget to delegate).
