Hi there!
Does the plugin support switching of .mo files - if existing?
For example, I will my store in German and Dutch language - and WooCommerce already has these 2 translations on board. So there's no need to translate the nearly 1,700 strings with your "String Translation" extension, right?!? -- The "String Translation" interface is not that useful for this massive amount of strings!
Switching the existing .mo files on language change is far better, and webmasters could also use the "Mo Cache" plugin which really speeds up the site!
Thanx, Dave from Germany :)
