(Get the code!)
I think about something that could work but should be implemented in libinput.
It's like in mathematics : functions can be coutinuous or discrete. Touchpad simulates a continuous function and we would like to have a sort of steps which are not continuous but discrete. Mouse just have discrete scrolls. We have in reality two types of scroll : the continous-scroll (now implemented) and the discrete-scroll (should be implemented ?)
Discrete-scroll means define steps, one step equals to one discrete-scroll. Many ways could be imagined : wait some time (0.2 sec), change of speed (decreasing then increasing), position of fingers (a minimal distance). I love the change of speed^^.
But then, applications must use the discrete-scroll and not the continuous-scroll to work properly depending on the situation (for example, continuous-scroll for firefox web pages but discrete-scroll for firefox items menu). Continuous-scroll can be the default one.
