Using changeset 89300 (and earlier version 2 builds), there doesn't appear to be a way to split the document layout both horizontally and vertically (see attached). Not sure if that's a bug or something that just hasn't been done yet or something the application (MVVM test program) needs to do differently.

I understand that VS2010 works this way, but is there a technical reason not to allow mixed orientations? When you place the first pair of documents on a document pane the overlay offers both orientations, so why not have a flag to AllowMixedOrientations?
