I made an app to: display web sites and files, highlight and drag noteworthy text or images into an item in a note outline, associate a comment with each note, drag a group of relevant notes into an item in a report outline, associate each group of notes with a word processor draft, and combine these drafts into a report draft. I couldn't sell a single copy so, I let the app die. Potential buyers already have a suite of apps to do this, and they are comfortable with it.
