Scott Kelby, President of the National Association of Photoshop Professionals (NAPP), posted a wishlist for Adobe Lightroom 2.o on his blog. He based his wishlist on messages from people he trained in 2007. Some items are really interesting. If you want to read the entire list check his post. Here are some of the items of that list I like.

The JPEG processed look
People want a way to get the exact same look as that JPEG preview applied to their raw photo as a starting point.

Photo books
Create printed photo books in Lightroom like you can do in Adobe Photoshop Elements, Apple iPhoto and Aperture.

Aperture style loupe
A loupe with the same features like in Aperture.

Extra light table functions
A light table where you can manually arrange your images.

Add more graphics
An ability to add more graphics to your slides and prints

Other items to add to Lightroom
Softproofing
Lenscorrection (Photoshopstyle)
Selective image adjustments like in Photoshop or Lightzone
