It would be useful to have the ability to add/attach working notes to tasks. That way we could document what has been done exactly to the task.
This could also easily done by adding an additonal comment field in the timebilling entry which is already bound to a task.

We use project management to fulfill gdpr requirements and need to document each working step done on clients server/equipment
