You can do this by adding an option to your Contextual Menu in the Daylite Preferences.
Do the following:
- Choose Daylite > Preferences> Contextual Menu
- Choose Tasks, and drag the "Worklist" option from the left side menu to the right side menu if it's not already there.
When you've done this, you can exit out of the Daylite Preferences.
Navigate to your worklist, and select all of the items on your worklist (holding down the "command" key will allow you to multi-select.)
Then right-click on the highlighted items and select worklist. This should remove them from your list.
