• [x] Preferences > "Reset Preferences" with German localisation (General problem: we must never give a text button a fixed width; if we want the default width of the button to be bigger, we can use the margins or minWidth properties. But never set width directly.)

Note: Please add any other text clipping problems that you find as comments to this issue!
