The bundles Logos offers are very interesting indeed and for those who cannot afford both, can have more the kind of resources one would desire as opposed to the base package. But I find that my efforts to assess the value of bundles is hindered by the fact that there is not, unlike for base packages, the ability to filter resources so as to show what would be new to a specific user.
This is an important drawback and I think it would really help potential buyers (and quite possibly generate more sales) if this feature was implemented on bundle product pages.
