In theory some translator should be able to log into the system, and for a single bundle, and for a single language (or multiple?), be able to continuously add translations without having to return to the main 'keywords' tab. In other words, once one translation has been done for one keyword, the translator can click 'add next translation' and the next keyword appears with the form appearing.

This would save translators time, and provide a nice workflow for translators contracted for example to add translations in a particular language.

While working, it would also be motivating see statistics such as % complete.
