Please add possibility of bulk adjustments in Lightroom over previously edited images. I can explain - for example, you edited in LR big photosession with thousands of pictures. But if you decide to add exposure, for example, + 0.3, or +0.7 for all pictures, it's impossible to do, because usually edited exposure value is very different, and different from picture to picture - for example, exposure value for a continuous line of pictures in one photosession is: -0.5, +0.1, +0.2, +0,2, +0.4, etc. The same situation with WB - if you decide to do all pictures more warm, or cool, it's impossible to do at once, and you have to do this adjustments manually. Especially often such adjustments needded, if you got pictures with LR catalog from another photographer/desigher. And such improvement can speed up workflow very, very well.
