This screen shows you how much time you spent on different activities. The groups are shown in the top portion of the window, and the window titles in the selected group are shown in the bottom.
Groups can be created automatically when TimeSprite finds similar window titles, or manually by assigning window titles or automatically created groups to a different group.
When you assign groups in this window, it applies to all times. When you assign a group to a window title in the lower list, that window title will always be assigned to that group. When you group an entry in the list of groups, entries that are would have been grouped into that group will be put into the group you specify instead.
