Browse for Subtitle Files Using 'Get More…'

Could you add more options to select a subtitle from the “get more…” not only by downloading from opensubtitles, but also by browsing the same folder that the video is in. Also if the video is cloud hosted I can browse in the cloud for a subtitle.

So the choices would be something like this:

Opensubtitle
Local to browse manually in folders at the same device
Network to browse manually in folders hosted in a cloud i.e. gdrive

the same way is implemented in nPlayer.
