🔖 Feature description

The request in #1604 was for:

group by (due date|priority|...) with task count - allows including a group task count in the group by header.

That is certainly one option. If there were multiple group by lines in a query, something would need to keep track of which ones needed counts and which not.

And alternative option would be to have something like this, which would apply to all levels of grouping:

show/hide group task count

similar to the existing:

show/hide task count

✔️ Solution

Complexity:

• Because tasks with multiple tags show up multiple times when grouped by tag, it will need to be clear whether it is counting unique tasks, or tasks displayed.
  • the task count shows unique tasks, so I think this feature should too.

❓ Alternatives

No response

📝 Additional Context

This was originally suggested in #1604, which proposed a more complex template-based approach.

Display of the task counts inside groups has also been requested by at least one user, soon after group by was released, but I cannot find the reference.
