Switching Languages fast
Is there a way to switch your "BASE" language fast?
I know you can click on the icon next to your "avatar" and switch languages fast there, but I am switching between the Base languages a lot. I think I saw a firefox addon or something like this once for this.
So I am practising: English from Hungarian (base=Hungarian),
French from English (base=English), German from English (base=English),
French from German (base=German), English from German (base=German)?
There is a userscript that allows you to do that: https://github.com/arekolek/DuolingoCourseSwitcher
