I would like to type notes into a picture. For example, I would like to name a building on a picture of a city. Or I just want to add a comment, a name of a person in a group or thousend other details directlxy in the picture. See a sample
+1 to this. Sometimes, for the sake of simplicity, I would like to add images to my lightroom library which are simply utilitarian (perhaps images of a home repair), where I would like to add notes to the image, or an arrow with a note, to provide some sort of localized reference for the future. When Paint can do something that Lightroom can't, you know there's a problem.
I agree this would be useful - overlay any field data (eg caption, EXIF) or freeform text. Can use watermarks on export but that only provides for standard text across the entire export - not individual images.
