The ability to track performance across all campaigns in one dashboard is very useful as well as being able see what's working or not from each campaign - it can be difficult at times when you are trying different things out but there are always ways around this too! It would also help if they could add more tags/categories so I don't have to search through multiple accounts just because something isn't showing up under 'lead' etc. If your looking into lead generation then using blupprintx has helped me with my needs by allowing tracking within 1 account which allows easier management than having 2 separate ones (which was annoying).
