The program allows you to create notes, papers and cards and sort them into specific folders to help you control your notes. I am wishing I had this application when I first started trying to research for my literature review. I may spend all night tonight and tomorrow trying to collect all my notes from papers and the sections I highlighted.
If you ever need to write a paper for academia, I highly recommend this program. You will not regret it.
A little off topic, but if you are interested in writing a academic paper or article for a journal you may wish to check out the book by Rocco called "The Handbook of Scholarly Writing and Publishing. The reference number in case you are needing it is 9780470393352. Check it out if you need help understanding arguments and what they should be structured like for a academic paper, or if you are interested in the process, as well as do's and don'ts.
