Track time by navigating to your selected timeslot. Press, drag, and release. Write a description for the entry and select a project and tag. In the side drawer, you also have the option to mark the entry as billable and choose who should be able to see it through the sensitivity option.
Now, we have a total of three entries presented differently. First, on the right, a planned entry which shows what is coming. Second, in the middle, an ongoing entry which shows what is going on. Third, to the left, a completed entry which shows what has been done.
If we check the key figures, we have logged time in the key-figure to the left, and total planned time in the key-figure to the right. To see the key figures for each day, hover on the day header. Logged time is shown in the key-figure on top, and total planned time in the key-figure on the bottom.
