It should start with the language the user selected for the phone.
I would also like it to help me use/learn a foriegn language. in my case
always show en and id, or make it easy to switch between those two.
With two features it could replace a lot of 'learn langX' apps.
1. Play audio of the word using recording on commons or text to speech
2. Sets/cats of words. E.g numbers and greetings/salutations
Ability to update/sync current page from witkt would be good.
