Hi, I wonder if there is an option or a plugin for converting an album from my FLAC library to MP3 for listen in my car.

Thanks in advance

Sadly not yet, I've been meaning to add this.
In the meantime you can write/find a script that does that, and launch it from the context menu by using the "execute custom command "... option from the export plugin.

Tnx for the reply. Did you tried a script for that? Cannot find anyone.
