- Handle special cases for languages where the number is not shown
- Rework the Downloader base implementation, allowing for more
advanced things to be done
- Separate the localization from the content country (just like
YouTube let's the user choose both).
- Hardcoded id and check at the first usage.
- As a fallback, and considering that the scripts containing the client
id were all split up, try searching it in each of them.
- Instead of downloading the whole ~1MB file, download just the first 16KB. With fallback to the old way in case of fail
- I've come across some technical difficulties as to how to limit the download (current implementation is too basic/simple for that), but in the end, a simple http header (Range) was enough
