Hi there,
this is just a "feature request", which might be considered in the future. No need to (hurry). I just saw, that you did not use WAI-ARIA (ARIA) in your code and it might help people with handicaps or special needs to get better access to your site. I know that it can be a lot of work, but as W3 recommends ARIA since last year it might be worth to check it out. The basics like "role", "aria-labelledby", "aria-describedby" or "or aria-label" shouldn't be a big problem, as you can fill them most of the times with already existing variables and strings.
I am not sure how interested you are in those kind of things. Just wanted to touch this topic. :)
