What is the reference manager that can show the list of annotations? 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?
Qiqqa will do this. 
Zotero will also do it, with the Zotfile extension (which can extract annotations from a PDF into a note).
