Yes have to say I agree on this one. Looks very much like they are already trying to integrate some of the features of Lightrooms crop tool into Photoshop, so maybe next version we will see it.
Personally never had any problems at all with Photoshops cropping. But this particular feature in Lightroom is indeed superbly implemented. In particular the ability to see the RESULT horizontal and smoothly represented in this way before committing.
The thirds divisions are also excellent. Maybe this could also be enhanced with an option to use Golden Section divider lines as well.
