Better controls on 7" Windows tablets
7" Windows tablets seem to be a trend this year, with several to choose from, even in some mainstream electronics stores. Opera is decent on those, but after trying Internet Explorer and the now scrapped "metro"-style Firefox mode, I realize the controls could be a lot better.
I've got an HP Stream 7 and I would adore a version of Opera tailored more to users like me. Also, some times the tablet, mobile or desktop version of sites works better. Perhaps include some sort of smart user agent and viewport features for those sites?
