I thought about this a bit more: Maybe it would be sufficient if the
hit area of the slider's bar would be a bid bigger. "Jump" also
probably is cool. But I'm not sure if it really would good if the
movement wouldn't stop when the stylus leaves the slider area. The DS
is a touchscreen, where the connection between stylus position and
screen pointer position probably should be much tighter than on a
computer screen where the handling is more indirect. Anybody knows
some UI guidelines or best practices for touchscreen interfaces
somewhere on the net?

Ah, I thought, movement was either radial or up/down. I didn't even
try left/right. It would be interesting to test radial movement. On a
computer screen this is horrible of course, but it may work on a
touchscreen, see above.

Another widget idea: Multisliders or [table] would be cool.
