Hey folks, many thanks for this great piece of software!
I do use Prodigy for my annotations for some time now. I would like to include a screenshot in a research work that will be published in the future to show the process. Is there any issue with the license (I am a research license user)? I wasn't able to find an information on this and this question might also be interesting to others. So what do you say? 
That's nice to hear and yes, including screenshots is no problem at all if it's in the context of how you used Prodigy etc. 
In fact, I think it's a really nice idea for visualising the annotation process, label scheme etc.
Also, feel free to share the results once they're published – I'd love to check out your work!
