Package and features matrix table
It would be quite handy to have a package and features matrix table to be able to compare the features in each package: Packages listed in column headers and features in rows. It would be even better if the matrix/table had check boxes to select/deselect features for each package.
Adding a row with check boxes to allow use of each package by resellers would be a nice addition.
Additionally, making an output that can be displayed to customers would help in defining/explaining the differences in the packages and features.
And it would be trivial to create an output to download into a csv file for off line use.
