At Omegawiki, it used to be that if you want to add 10 translations or synonyms to a word, you have to add them one by one. This implies that the page is reloaded 10 times. It takes time for the contributor, and load for the server.
But now, with a bit of java, there is the possibility to add multiple translations without reloading the page.
For this, you just have to click on the green "+" and a new row appears.
I give translations as an example, but it works also for definitions, classes, annotations, etc.
I am glad, it is my first steps in the AJAX world, and it will allow us to reach faster the 400k milestone.
