From ambassadors' chat (written by @Urbanecm):
@RHo Czech texts are (again 🙂) too long. I've already chosen shorter synonym for "Jednoduché" ("Snadné"), which does fit (at least when changing through browser developer console), but it's going to be harder for "Středně obtížné".
Would it be possible to indent the second line a little bit, so it looks better for Czech users?
