I'd like to be able to assign people tasks but prevent them from modifying the name, description, etc. of that task.
We define requirements, and anyone is able to modify the description of a task (or the requirements). Sometimes that's necessary, but would be helpful if we could list out or provide requirements that are then locked-in (or are only editable by specific users with certain permissions, or roles, etc).
Thank you for the request. It's important to note that we have many different types of user permissions within Aha! today. What you are describing sounds like a "Reviewer" or "Viewer" who would be users who would not be able to make edits to features as a whole.
Based on current priorities and feedback over time, we don't have plans to allow for permission-ing at the field level, but we hope that the system permissions can help. We hope you can understand.
