Yeah, but I don't know why they couldn't have just said "We're moving the buttons to the left to acclimate users and make way for a new feature we'll be introducing sometime in the near future, but are not ready to discuss right now." It would have been a lot nicer than their "because I said so" deal, which actually cost them at least one good developer (to my recollection; there was a story about it on here not that long ago, but it would be hard to find) who felt that Canonical became calloused to community desires.
