All of these new Portrait features, and yet it is nearly impossible to remove dust from headshots (fabric) without a trip to PS, as LR starts to slow down with dozens of clone tool stamps. D&S is also useful to remove long exposure hot pixels that are not automatically identified (night photography, etc.). This would simplify my workflow for several different things I do daily (including not having two 16-bit files residing on my hard drive), and I would think that many people would find it useful.
