Choose which categories to include in project/widget

This is a major factor for me, in fact I cannot use idea informer as it is at all because it just does not make sense for my website. In my case I only need the ideas and testimonials categories. I already have a system in place for questions so adding another place where users can ask questions will just confuse users and also make a mess of things, and if there are any problems I sure don't want them being public. This is just my case, I can see other projects where you would only need the problems and questions, customization on categories is an absolute must.
