Allow Aha contributors to turn private comments on from inside Aha by clicking a grayed out padlock turning it blue.
Usecase
Internal user (sales, support, etc) makes a portal comment about an idea that is better left for internal consumption.
Idea reviewer sees the comment was accidentally left public. Rather than deleting the comment if they could click on the padlock to make it private between the commenter and the back of the house that would solve the problem.
This feature would be very helpful within my organization. We often have clients comment with private or sensitive information and we would like the ability to quickly change these comments to private.
