We are a service agency, managing complex projects for our clients. We need them to be able to participate in our project boards without seeing all of our internal conversations on tasks – only if they are @ mentioned to alert them that the task is ready for review, or that we need an answer on something. We are currently having to kick up a second “mirror” board for each project so that the client has some visibility into the workflow, planning, etc. but it is a NIGHTMARE to manage. When will this feature be considered? Thank you.
