Dear Juan Carlos
Thank you for the valuable plugin, I've been using it for the past months and it works great.
Regarding Q2 - My students are submitting over and over to "hack" my tests. Of course I can penalize them, however this is not a good enough solution, as they need to think twice before each submission - something that I do not wish them to do. Also, they think it is petty and that it is some kind of a punishment. I believe that a better solution would be to limit the submissions to X times a day. It will stop the "hacking" as well without punishing them.
Is there any chance that this feature will be supported in the near future?
