What is your feature wishlist in Lightroom 4 ?
I'll share mine to kick the discussion - I tried to think of real new features, but obviously feel free to chime in about incremental improvements!
1/ AUTOMATIC focus peeking - show me which pictures are sharp and where, straight in grid mode. Allow me to choose the target resolution that defines peeking - some of my D800E pictures are "blurry" if I'm pixel peeping, but perfectly fine for a 10x15cm (4x6in) or for web usage. In survey mode, in many cases, this would allow me to choose the best candidate instantaneously.
2/ State of the art Face Recognition and corresponding auto-keywording - Adobe should just count the number of web articles describing how to leverage Picasa to emulate that in LR...
3/ Still on the subject of automatic recognition, an INTELLIGENT "find similar images" across all a library - academic research on the subject is showing incredible results - let's find some of that in LR4 ?
4/ AUTOMATIC straighten the horizon - Aperture does it, I shouldn't have to draw a line at the horizon or to the side of the building to straighten my picture, those features are visible enough in the photograph most of the time - "just do it".
5/ AUTOMATIC selection of series of consecutive or near consecutive similar images - Aperture does it. It would be great to be able to do that in survey mode, with a key to go from one series to the next.
Re-reading my list, I'm realizing most of the enhancements are addressing the editing workflow, rather than the "develop and process" - it's probably that I really can't see what's missing... I'm on Adobe's Creative Cloud, so, for complex edition jobs, LR4 and Photoshop together have all that I need and (much, much) more.
