Working in Django with the Python plugin, we don't seem to enjoy the power of IntelliJ's amazing localization tools. The "Django way" (http://docs.djangoproject.com/en/dev/topics/i18n/) seems to require using .po files for each locale, which get compiled into .mo files. (http://www.gnu.org/software/gettext/manual/gettext.html#Files)
I'd like to request that JetBrains consider extending its il8n tools to provide support for these formats in addition to the Java properties it already supports. It would be excellent to have IDEA's localization system available in our Python/Django projects.
If this already exists, but I just missed it, then someone please set me straight. I'll love you for it!
