I would like to see the (Comments) panel in Lightroom made available to use for individual photo files. I understand that panel is currently only applicable to collections shared thru Lightroom Mobile or Published Service connections.
I would like to see a comments ability as well, but preferably as a sticky note that pops up when you hover over a photo. Or a notes panel would probably be ok too. I may have taken a couple of series of panoramas, and want to add a note for myself to each about the settings I used, the type of development I want to do later on them, etc. Basically a place to jot down quick notes about an image or series of images.
