For those of you constantly changing between languages, or travelling a lot, and need constant translation - Google Translate has just added a valuable new ability - Phrasebook. Phrasebook allows you to save your favorite translations into a persistant, searchable list.

All you have to do is click the star under the translation to add it, and go through your Phrasebook using the search box in the top right hand corner of the screen. It might not be perfect now, but like most Google services, it'll continue to improve and hopefully one day be an app that can be quite useful. At the moment, you can't edit the text of a translation, which is a bit of a hassle.
