I love what I think I've seen you call "bump stop" or something like that in the Properties dialog when setting the control color. It's the feature that bumps and pauses the slider momentarily so you can release and get the selected color.
Would you consider that for actual sliders/faders? Even on larger sliders, I often release them only to have the value shift by one or two. Many of my sliders are "Send on Release" and I too often send the wrong number because I just can't lift my finger straight off.
Thanks.
