It would be great to have a field for "personal notes" during the Lightroom Develop step. During my import workflow I walk through all of my picture the first time, delete bad ones and rate better ones with stars. Sometimes a good idea comes to my mind (how I could edit the picture), which I would like to fix to the photo. It would be perfect to have a comment field for personal usage, which gets saved in the Lightroom Catalogue, but not in the Metadata of the file. I thought of the implementation similar to the PDF comment feature in Mendeley. Each picture can get a note, at the end I can get an overview of all my notes, which are still to do. It would also be smart to implement the ability, to filter for photos with/without notes.A simple workaround, which is currently doable, to mark a picture with a certain color (which I associate with something), isn't enough. Similar to Mendeley.[Currently using Lightroom 3.6 / Win7 64bit]
