Integrate Subadub UI into Netflix subtile menu

[chriskempson]

Thought it might be nice to place the UI in Netflix's subtitle menu like Netflix Subtitle Downloader does:

Neat idea, thanks for the suggestion and mockup! Though if I end up making Subadub also work with user-imported content and perhaps YouTube, it might be better to be consistent and separate.. we'll see.

Just my two cents. In the current configuration i can display both Netflix subtitles and subadub subtitles.

This is super useful as it allows me to display two different languages at the same time and this suggestion looks like it might break that "feature".

I currently play two sets of subtitles at once as well

Don't worry, it wouldn't break the feature 😃
