It often happens that you can be working on the same activity for an extended period of time. In Rodeo, you can make a time card for such an activity as a favorite. This way the time card will appear in the ribbon.
When you start work on another day, all you have to do is click on the favorite and enter the amount of time that you have spent on that activity.
When the activity for your favorite time card is finished you can delete it by clicking on the edit button in the right-hand corner of the ribbon.
