PR with this is here => #4719

edit: no, it's part of #4613 now. When doing translations, it may be an idea to download a copy of Qt Linguist - i.e. from https://github.com/lelegard/qtlinguist-installers/releases - as it will ensure there are no mistakes in the tags/formatting, and will make it easy to see which translations are unfinished / still need doing ;)
