Ah, of course.
Probably not all that difficult to whip up, at least in a quick and dirty
form.
There is a function in the library called fl_drw_slider() which allows
you to draw only the slider knob, so you could, in theory, draw any number
of knobs on one slider.
I'm kinda booked at the moment or I'd take a hack at it. The manual gives
pretty good instructions on how to create your own objects if anyone
wants to prototype something.
