That would be great if that were exist for someone that can't find new manga.

You pretty much can. This is just a database so what you find is what you can search up for. Whether it has been translated or not is depending on the MU database tracker. If you're trying to find a reader page to search, this isn't the place for it.

There is already a thread regarding Finding Manga. You can also use the search to find result by genre and see if any of it is translated then use your search engine to find your results to read.
