If you work on tasks that recur frequently, you can add them to your favourites, so you will be able to start them in no time.
Creating favourite time logs
You have a few different options here:
if you save your favourite time log without entering a duration or start and end times, the counter will just start ticking when you select to track time on the favorite log.
If you save it with start and end times, it will be added with the same start and end times every day you select it.
If you save it with duration only, it will be added with the exact same duration and without start and end times.
