Hi,
I'm trying ktouch (stable)on Debian on a raspberry pi (up to date). In the documentation found here https://docs.kde.org/stable5/en/ktouch/ktouch/training_preparation.html#configuration_dialog they speak about a button in the tool bar of the home screen but I cannot find it. Did anyone had the same problem or I'm not looking at the right place?
Thanks a lot.

In fact I'm using dark mode that's why I cannot see it. I have to click it "blind" at the right of the top toolbar of the home screen.

really good advice! thanks
