Add ability to hide unused tabs in projects

While I know we can export content into notebooks for others to see, thereby selecting which content to feature/ignore, but I am wanting to simplify some products/lines for those working on the project within Aha rather than just viewing the reports. For example, I love the new Personas and Competitors features, but on some products, they don't make sense to be there, so I'd love to be able to disable them for those projects, similar perhaps to how you can enable or disable SCRUM Boards or the Ideas Portal within products (although a simpler interface would possibly be to just have a "hide this section" checkbox on pages such as the persona's overview page and the Competitor overview page.
