I am using Mendeley to organize, highlight and to synchronize my references. I think a feature where you can see a list of annotations/highlight that you have made will be extremely useful during writing.
For example one day you just remember, "Oh I have seen this in some papers, I don't remember which one but I remember I highlighted it."
Right now I have to guess and open one by one the paper to look for the annotations that I meant and scrolling the screen to look for "it", or by performing a search, both are not efficient enough.
Kindle has this feature. Everytime you make some annotations (on different books) they aggregate and put it as a list for you. When you click on that, it will go to the page on the book.
Is there any reference manager that has this kind of functionality?
