I admit I haven't looked at the KDE tool since so I can't comment on it too
much. fwiw, the list of configuration options exported by libinput is here:
https://wayland.freedesktop.org/libinput/doc/latest/group__config.html
Note that unlike synaptis/evdev, not every option is available on every
device though. for example you won't get configurable click methods on
touchpads with physical buttons.
