I'm writing my dissertation on latex, and this involves several reviews from my mentor, of course.
I currently use the package
soul to highlight changes from the previous versions and comments, but I would like to use the same scheme he uses to annotate the suggestions he has to the text, which is annotating it with adobe reader, so it gets highlighted and a little balloon with the desired text is created like this:
I don't know if this is adobe proprietary stuff, but I think not since it seems to work fine on others pdf viewers.
So the thing is: Is there any package that provides the possibility to create those notes into latex?
