I believe that the popularity of the Brave browser would be decisive if it were to have a gTranslate-style small, lightweight and completely unobtrusive translation assistant. Which allows you to conveniently and easily check the translation of one single foreign language word.
I really miss some “gTranslate-style addon” which would, if necessary, appear to be a translation of the foreign language in the text of the browser in a small unobtrusive pop-up window. Not whole web page. Not the entire webpage, nor anything else unnecessary and distracting. Just that little word.
