@ A @ do you like, annotate journals and stuff you read?
Yeah on my computer though. I usually take important stuff out and put it in a word document with other related stuff and then just highlight my pdf. Or draw a box around a figure, which is always purple because I don't know how to change the colour of boxes in preview. I don't know much about computer. I have a terrible system for papers, everyone hates it! I refuse to use a paper organising app, such as Papers, so as a consequence I have about 300 folders on my computer that each house a specific paper and its associated word document for note taking. It's excellent and old-school. I just don't understand new technology.
In any case, if I get offered free software next year I might move over but muurrrghhhh.
