More Photoshop like clone/healing brushes in Lightroom!
I love retouching in Photoshop, especially with the content aware fill with the healing tool, but Lightrooms tools are clunky. I don't know if there are technical limitations to implementing tools like Photoshop's in Lightroom but it would be GREAT!
I would rather be able to get a baseline retouched image in Lightroom than having to edit in Photoshop and then come back to Lightroom. I would rather just use Photoshop for image alterations.
