Step 1: the category
The team's categories, each with the time you already logged this week.
Manual entry happens in two steps. The first one is the choice of a category in a list.
What each line says

Every category has a colour, on this screen and in the charts. The colour cannot be chosen and never changes.
On the right, when there is one, sits the time I personally logged on that category this week. The point is not to build a dashboard, but to answer the question you ask yourself right before typing: have I already noted this, or not?
Archived categories are not offered here. They stay visible in the statistics, but you can no longer count time on them.
If the team has no category yet, the list gives way to an invitation to create one, and the “Manage categories” link waits just below.
