A number of folks have found it odd that selecting a language doesn't change the localization of the app itself (as it would on the web site). This could be a nice change to make.
We also support more locales than any given Android setup likely does, including those that it doesn't recognize at all (3-letter codes). Allowing folks to select their locale even when it's not available in other things on their phone might be nice!
