I found out about this on tumblr and used it today with the daily I drew. If you're an artist who like to use references a lot or like to try and have references on the same screen you're using you could give Pureref a try. I'm personally very happy with it having only used it the first time :3c

It was a little confusing for me using this for the first time and there is a lot of control so here's a video I've found that shows some of the commands if you want to give it a try.
