Currently, I am unable to adjust opacity of layers or strokes with my WACOM Intuos without specifying a keypress for each Opacity Value (0-9). In addition (or replacing) current Opacity control of a keyboard number, I propose an Opacity Up and Down key combination so that my WACOM Intuos Touch Ring can adjust Opacity like Photoshop or Krita. Additionally, I'd love a setting to adjust how much opacity is changed by each key-press. (Instead of a flat 10%)
