As an Idea administrator or Product Owner, I'd like the original submitter to be unable to edit the idea that is in-progress or shipped, so it does not look like we implemented their altered narrative.
Either admin editable in custom statuses, or simply disallow for built-in status categories "In-progress" or higher.
This is a big problem with AHA as i see it.
The submitter should now be allowed to edit the original idea after it has reached a specific state.
The administrator that manages the ideas should have the power to lock a idea so it is not editable ( and unlock it aswell perhaps ? )
