Disable internal comments in idea workspaces

What is the challenge?

Our idea portals are used internally; we have users that only use the portal interface or the backend interface (depending on their role) to view ideas. When the backend users comment, they gravitate towards internal comments, which don't appear in the portal view.

What is the impact?

Users who are more comfortable with the portal interface often miss comments that are posted internally.

Describe your idea

Have the ability to disable internal comments, so that all users, regardless of where they are viewing the idea, are only able to create portal comments.
