Many of us work on laptops, always on the go. The two finger touchpad scroll has become a standard.
In the modeler, this works for vertical scrolling, however it does not work for horizontal scrolling (most used). So, one still has to navigate the pointer to the scrollbar all the time.
It would be wonderful if this were fixed.
Since a few weeks, I now use a vertical mouse where the middle mouse button is really a button. Using this middle mouse button made me scrolling almost unnecessary!
