Cut things down to 3 versions

When I purchase something that has Professional in it's title, I would expect this to be the version that has all the features.

This Pro version is too crippled in features for it to be considered so and as such, will likely put people off purchasing.

Based on the premise that this software does do all that it can, which based upon the number of sites supported is in it's favour, you might also look at lowering the price to make it attractive to a far greater audience that would happily part with $10 or so and make more profit from selling far more to the masses, rather then a few to enthusiasts.
