The wheel/slider mapping must be the same system-wide 2. Wheel-up should increase, wheel-down should decrease. I would write "must" here, if it wasn't for the problem with point 1. I wrote to the GTK list, but nobody seems to care. I don't think this should be configurable, because it has been shown that the proposed behaviour makes more sense. If we introduce options for things like this, we will end up in configurability hell. So it should be about making the GTK and QT folks see the light, or only using fan-sliders which are different enough to behave differently. --- Thorsten Wilms
