Add language details feature

[alex-bender]

Hello!
It's really nice tool, thanks for that!
I'd like to suggest one improvement -- add language details bar to hover.
I've been thinking about implementing such extension by myself, but looked around instead, and found your repo. I think that at least main language will provide better user experience for your tool.
Thanks

Sorry, moving to fast. Didn't notice that there is main language already. So the question now is only about the lang bar. But I assume that answer is no..
Anyway, thanks for the tool and sorry for bothering you.
