Hi PILOU
It looks great! Thanks for your contribution. :)
It's ok if translated descriptions are shorter or longer in length. You can write any description with any length. It'll fit in the tooltip box automatically.

Ok, but, I think it is almost a complete list of words.
Yesterday, I improved the searchbox, So, You can search nodes in your language.( EN, FR, RU )
It doesn't need any additional translation. :)
