Ok I just made a new app!
It uses a totally different kind of method to remember the voc than the other app, it's called "passive learning" and you'll understand why's that:
There is no window in this application, just an icon on the system bar where pops up a message sometimes with a word and its translation/kanji/type. You can adjust the delay between messages (default is 1minute), pause or resume the app when you want and choose between the levels 2, 3 and 4 of the jlpt test.
here is a screenshot:
and the link:
Happy passive learning
MAC USERS: It doesn't work on MAC! until a stable 6.0 version of the Java virtual machine is released the behavior of my app is unknown, but once it's released you should be able to use it right away.
As the application uses a system protected place (the task bar) it requires that you allow the application to use it so when you're asked if you're willing to do so (certificate thing when you click on the link) please accept or it won't launch.
If some of you are reluctant I put the sources of the app in the jar file so feel free to have a look
