The solution is not so simple. Tool presets works fine until 2.6
series when all brush
dynamics are implemented as a tool options, but since the introduce of
you cannot remember and restore all of the presets by tool presets.
For example, assume tool-preset-A and tool-preset-B are sharing same dynamics-A.
When you choose tool-preset-A, dynamics-A is selected as its dynamics, then
change the value in dynamics-A, and save it. The operation lead to the
behavior of tool-preset-B because it also uses dynamics-A.
So, to avoid the confusion, you should separate the dynamics used by
from one used by tool-preset-B. and when you define the new tool
preset, you should
also define the new dynamics too.
I was very annoyed by the complicated tool preset management, and that
is one of
the biggest reason to abandon the current dynamics implementation and introduce
the MyPaint brushlib into the GIMP.
