Not sure how new this is (or if I've missed this all along? pretty sure it's new since Keith recently commented on tumblr that they were working on the mobile site), but while adding wiz tokens to my currencies a few minutes ago I noticed there's now nice fancy pop ups on mobile:

It's avery nice chance and I really hope to see more 'mobile/tablet' friendly design changes in the future c:

that's because of an iOS update I'm pretty sure, nothing the site has done.

[edit] it was first mentioned in this thread :)

Keith did mention that they were working on the mobile site I believe though, so maybe some new things are in store for the future - mobile-friendly-wise ( edit: which you did state you read, I am not good at reading haha. )
