Hi, as a digital painter I use a lot of brush adjustments of the fly. One of them is ALT+Right Horizontal Mouse Drag to adjust the brush size. However, there's a function that also changes the opacity while you drag horizontally. As you paint it's quite easy to swipe at an angle and therefore unintentionally changing the opacity of your brush. At the moment there is no option to disable the opacity change, which is really frustrating and disrupts my workflow quite often. It would be great to have an option int the tool section to disable the opacity change based on HUD movement.
