I'd like to see some kind of display for a given manga for all the various languages it's been translated into and maybe some way of showing, temporarily, the chapters of that manga in a selected language without having to set and reset my global language preferences and/or restarting my browser.
There are a few mangas I follow that seem to have been abandoned by the scanlators in my primary language, English. If they have more chapters in another language I might be able to read forward with some difficulty in that other language.
