It has excellent documentation, which makes it easy to use with other people in your field or lab who are not as familiar/educated about finding software like this out there! I wish that we could have access from our computers while at work (instead of downloading an entire program) so everyone can be using different versions without needing someone else's computer all day long haha - but aside form those two things i didn't really find anything bad!! The ability to mark up documents by highlighting search terms then adding notes afterwards would make organizing research papers much easier when you cannot share them easily between students etc.
