In older versions of Evernote it was possible to use more languages for spell check. How? It was possible to copy the OpenOffice dict. files in the Evernote dict folder. Newer versions do not support this anymore. I know many people in Greece who don't use Evernote as their main note taking app because of the lack of Greek spell check support. Also for people who translate a lot, more languages are needed to be included in the spell check options. If the language packs are available for free and are in the public domain, I guess this is not difficult at all to be implemented.
