I have a look at it every now and then to see how it's evolving. Last time
it still was limited to stereo, and it crashed within minutes. Which does
indeed mean I don't use it.

> But you are correct that the pan/gain 'indicators' have less precision then

There's a simple rule: if the indicator says '-3.0' then the actual value
should be -3.0. Not -2.96 or -3.04. In other words the indicator should have
the required precision to be able to show *all* possible values exactly.
Steps of 0.1 dB for gain are perfectly OK, even bigger ones. You have
to 'smooth' the transition anyway if the gain changes.

> Right now gain increment steps are 0.05 dB for gain, and there are 200 steps

I hope '200 steps' means 201 positions. You need an odd number in order to
have a central position.

Real ones provide support so the user can hold the knob without moving it even
in shaky conditions.

You can, and in fact the sliders I'm using in some new projects do have
sub-pixel accuracy, also visually.

> Traverso does away with that by using the relative mouse moving distance,

Relative motion is the only one that makes sense for a slider. There's nothing
more useless than a control that jumps to the value you click on.

> Side effect is that the mouse can be moved physically

Which in general is a good idea. OTOH, fader attenuation should 'go faster' for
low gain values (e.g. below -40 dB w.r.t. the maximum), so a fixed step is not
always optimal.
