Thank you for the excellent feedback. Let me see if I can address your issues:

1. This is actually by design, it's just supposed to be a list of the installed languages. Perhaps this doesn't make sense though, I'll investigate this for version 3.1.9.

2. Another excellent idea. I'll investigate changing the register key to accept a language file ID (like 'FR') instead of showing errors for all languages.

3. This has been bugging me lately as well, and will probably be moved to a temp folder somewhere.

Thanks!
