In idea submission form, if there were visual indicator if the campaign is private or public, would help idea submitter to get insight about privacy of the newly submitted idea. Sometimes, a campaign title is not enough to know if I am posting in right campaign. A visual indicator (a lock icon or a color hint) would help the idea submitter to understand the scope of submission quickly.
*Usecase*: I am submitting to idea to a campaign which is private to my department. If there is a public campaign for my department, it may become difficult to understand quickly where the idea is going to show up.
