All you have to do is to download the MyPaint, try it, and see how the
parameters are
handled. Basically they are hidden from users because "Brushes" has
many presets,
and users can tweak only few key parameters in simple parameter
setting popup dialog.
And users can still tweak all parameters from another complex
parameter editor dialog.

While in current snapshot of the GIMP, Parameters are scattered over
dynamics presets and tool options presets. To make it worse, changing the value
of the dynamics directly affect other tool presets which shares
dynamics presets.
You should take carefully the dynamics and tool options, and you
should know how those
parameters related with each other. It is too complicated than the
handling in MyPaint.
