The Landscape Mode in the BBM application will be supported directly, which means there will no longer be any need to view your messages from the Hub view. Apart from that, there will also be Multiple Picture Transfer support from the Pictures App, which lets you take advantage of this unique function through the Pictures App itself.
As mentioned earlier, this is but limited at the moment, so do not fret if you have not quite gained access to it, but it should provide a certain degree of comfort that it is already in the pipeline, so the masses should be on the receiving end of it not too far down the road. One must admit, the ability to perform multiple sharing of pictures from the Pictures App is quite a coup.
