UX: Better hint that language is selected

[cmelchior]

With trying to select the language you want instructions for, the only UI hint there is is the language under the icons changing. That feels a little too subtle for me. It could be nice with a stronger UI response, like either a box around the icon, perhaps inverting black/white inside? or making the icon colored.

Just suggestions.

Would increasing the contrast work? Or perhaps dimming out the other icons.

Hey - looks like you forgot to add a T-* label - could you please add one (if you have access to add labels)?
