Very good Extension with many custom options to Adjust. Which this will might be too much overwhelming for many users. You must take a little time to play and experiment with the settings, to see which one fits you most and make your workflow convenient.
* The only thing I don't get is From where does it takes those translations? I mean it is completely different from other similar Addons who use the google translate original webpage to perform the translations... BUT the Translations from English into Greek are Excellent!! Can someone tell me what translation software does this addon is using?
