What else does it do?
Oh boy... one of the features of for-pay Blogger Pro is to be able to rearrange the items on your weblog.
Now would be a good time to mention that that's been a feature of Free-Conversant's weblog plug-in since day one. (notice the "Free" in Free-Conversant)
I think it's great that there's a revenue-generating version of Blogger (I've never used it, FWIW), but for the sake of Blogger Pro users, I sure hope that's the weakest of the exclusive features.
