/usr/share/apps/ktouch/german.ktouch.xml Exercise line <Line>Grundstellung</Line> in the middle of level 1 is highly questionable. I have strong doubts the user is expected to type that word as an exercise which is completely different from the rest of level 1.
Created attachment 151489 [details] patch against kdeedu-3.5.6
