First of all thank you for the plugin, I love it.
Here are two feature requests which I think would make it even better:
1. A "processing animation"
When you click on the button "results", the results appear instantly. I think that it would be much better if there was a small animation beforehand, indicating/faking that the system "works" to put the results together.
Most quizzes have this. It makes the quiz a little more trustworthy.
2. A better CSS support
Maybe a custom CSS box, or something like that. This would make the graphical adjustment to individual sites easier.
Thank you very much for considering.
