Q: Rearranging apps in Launchpad

This is more of a cosmetic question than something of any great significance/importance, but is there a way to rearrange the way apps are laid out in Launchpad?  I'm a bit OCD when it comes to organization, and I'd prefer to have them all alphabetical if possible.  The top three rows on the first page are all apps that come standard in OS X — they're not alphabetical.  The next two rows are apps I've downloaded myself — they're not alphabetical.  The curious thing though is that on the second page, all still apps I've downloaded myself, those are alphabetical.  Can't figure that one out, myself.

So, is what I'm rambling about possible or do I just have to deal with it like it is?  Like I said, it's purely a cosmetic thing, I just thought it was worth throwing out to get some feedback.
