This is my own layout based on colemak dh tailored to my own german needs. It is a nobrainer to me that a control backspace is as important to the normal backspace. Most of the time I tent to rewrite the whole word instead of spamming Backspace. Navigation is important: With my index/middle/ring I can press all the arrows without changing the layer. The navigation keys like Home/End and PageUp/Down is right underneath them. with my pinky I can do control and with my thumb shift. I don’t have to rely on vim or other software to give me a good text/gui navigation experience. I have a dongle with wich I can connect to other peoples' PC and feel right at home without changing the input method.
