It would be very useful if users of localised MBz UI could search instruments by English name (in addition to localized name). Lots of artists worldwide make music in English, often with booklet or liner notes in English as well, and while it's easy to tell that e.g. "guitar" in liners should be entered as "kitarr" in Estonian localisation, it gets difficult with instruments like cajón = kasttrumm, or harpsichord = klavessiin, or slide whistle = kulissflööt = džässflööt.
My idea is that when one enters e.g. "guitar" in instrument selection box, "kitarr" would get selected (instead of no instrument found), preferably with a little note saying something like "You searched for "guitar", which is English for "kitarr"".
