What do the yellow blocks represent in the “Timeline” view in Toggl Focus?

Hi everyone,
I’ve recently started using Toggl Focus for team planning and I have a question about the Timeline view.

When I assign estimated hours to tasks, yellow blocks automatically appear in the person’s timeline (see attached screenshot).

I’m not completely sure what these yellow blocks represent:

  • Are they auto-distributed planned hours based on the estimate?

  • Do they indicate available capacity or already allocated capacity?

  • Do they reflect the total task estimate or a daily effort distribution?

  • Are they editable, or fully dependent on the user’s working hours settings?

I couldn’t find any official documentation that explains the meaning or logic behind these yellow blocks.
