Bizarre translation

See the menu:

"Refaktorisierung" sounds very strange to me. Wikipedia reads: "Refactoring (deutsch auch Refaktorierung, Restrukturierung oder schlicht Umgestaltung)". Each of these words is better, I think. I like "Restrukturierung".

"Id" should either be "ID" or "id" - or be left out completely.
"Umbenennen" should be lowercase.
