Here are some ideas to date. Are there others?
New fields for all notifications:
• Contact person
• For required: Consequences for not completing task/attending event
New fields for events:
• End date
• End time...
Currently the menu in the widgets' title bar (UI element: downward-pointing triangle) has a single item: "Hide". The UI element is only visible on rollover.
Users may want more information specifically about their My Tasks and My Events...
