It would be beneficial to Product Line Managers and Product Managers if individual custom components could be hidden from some individuals. This is useful when adding sensitive financial data or other secure information. If the Product is shared for Reviewers to see, they would see all components. We would like to be able to hide some of those components from specific users.
As you already know, we currently have 4 tiers of users permissions within Aha! (product owners, contributors, reviewers and viewers). We have spent much time gathering feedback from the community in constructing these permission levels. We don't currently have component level permissions, but one workaround would be to create a new Product and include some of the more secure information within a product that only some users have access to.
At this time, we do not have plans to make changes to the user permissions model based on community feedback and our current goals and initiatives.
