I would like to be able to apply the HDR Toning adjustment to a single layer without having to flatten all the layers
It would be nice to be apply to apply smart filters to multiply layers instead of only a single smart object.
It would be nice to have a list view similar to what was in Aperture. It would make it easier to sort and organize photos.
It would be nice to be be able to add an adjustment layer that allows you to apply an editable vignette.
I would like to have the ability to add a simple temperature and tint adjustment layer in Photoshop.
