Possibility to add comments
Make it possible to add comments to the different References that you include or exclude.
You could do this through the labeling feature although this may clutter the list of articles if your labels are too long

The labeling function is not good enough for this, in my case I have ended up with a thousand labels, making the labeling out of order and not possible to use. So I really mis an own comment box were you could make comments to the spesific article - so that you dont have to read them all over and over again. Or at least a possibility to highlight Words in the abstract -making it easier to read them faster the second time you read them.
