For convenience, it would be great to have a subtitle button next to airplay for quick access to subtitles. Just one press for selecting the first subtitle or maybe a small menu with the choices that are available.
This would greatly help out switching between shows in different languages where sometimes no subs are preferred and other times are necessary.
Btw, thanks for finally releasing macbook version. In my opinion, infuse is (one of) the main reason(s) to buy apple over all other products.
