I've been playing in GIMP and I'm getting close to a layout that I really really like! Problem is, now I don't want to cover the colors on the CP with a black mounting plate. Is there a good way to undermount the trackball without seeing the bracket, or a bracket made for this sort of thing? No carriage bolts or plate showing? I have the undermount invisible stuff for the joysticks, would like to keep it clean with the trackball too.Thanks!!!
