Display number of open pins and tasks in project list

Description of the request:

In the project list (start view), the number of open pins and tasks per project should be visible, similar to the plan view. This allows project administrators or subcontractors to see at a glance where action is needed.

Example scenario:

A subcontractor manages 40 projects simultaneously. By sorting by open tasks or pins, they can immediately focus on the most urgent projects. Project administrators, in turn, get a quick overview of the overall status of all projects they manage.

Functional requirements:

• Display of open pins and tasks directly in the project list

• Visibility according to roles and permissions (subcontractors only see their own open items)

• Sorting option by number of open pins/tasks

Added value:

• Faster prioritization of open issues

• Greater transparency in the project portfolio

• Improved user guidance for many parallel projects

• Fewer clicks and less manual effort required to check status
