Hi Pierre,
Thanks for your offer of assistance.
I'm currently investigating the Synology angle, so will come back to you on your specific post about that. We can then take in more detail about what may be required for that.
I would be very happy for any translation help for the app, into French. If you are technically minded, you can checkout the code-base from github. The README gives details on what to do.
If not, let me know, I can send you a zip of the 'key translated value pairs' in a file.
Regards.
Wayne
