After using LR 4 for a bit, I'm still looking for an efficient workflow for parsing my photographs like I used to with the Pick Flag and collections. Now that you have taken away the local flags, I'm wasting all kinds of time trying to filter and re-filter my images down to just the best ones. LR 4 seems great in all other aspects except it is wasting my time by forcing me to somehow develop an entirely new workflow. I can't seem to get efficient with this version at all. HELP!!!
