I added the Google Translation Button feature to the Web Application. It works nicely, I think, though it does cause the page to jump slightly after loading while the button itself loads (presumably due to having to leap over to google for data updates, or something). I can not actually validate, however, that the translations are particularly meaningful, as my skills at foreign languages is limited to asking how to find the toilet in French. However, it seems to work nicely, so I'll go with it on the assumption that even if it is not currently perfect, the service will only improve over time. Hopefully.
