I wish Studio One had an option to assign Right Click like Logic Pro, having it locked to Toolbox or the menu is limited. Being able to use left click, cmd click(middle mouse) or right click as tools is such huge power feature in Logic, I rarely need to change tools and that can easily be assigned to a KC.
