I would also like to request that Topaz Sudio start supporting Photoshop Smart Objects. I always use Topaz within Photoshop, and the plugins DO support Smart Objects; but not the Studio apps, like Detail. It's a real pain not being able to use Detail and the other Studio apps as SO's.
Also: You need to make it clear that Studio does not support Smart Objects. They DO half-way support it, in that if you have a Smart Object layer and attempt to open a Studio app, it opens just fine and lets you make adjustments without any warning that you won't be able to come back and make edits later. Worse, any other filters that are run later (e.g., Adobe Camera Raw filter) on that layer also can't be opened and edited. So running a Studio app on a Smart Object layer ruins the entire layer.
