thanks for your fast response :)

1. Why don't the brushes show their real size when aktivated?
The tool seems to adopt the settings of the previous used brush.
The size of the brush is set by the Size setting in the options of the
painting tool you use. Thus a brush no longer has only one intrinsic
This is not very handy, because brushes made from pixelgrafics don't look very nice anymore, when they are scaled bigger. And why should you make brushes in a special size, if it doesn't matter in anyway? Ok, I will get used to putting a brush back to it's original size, but it really isn't very handy.

2. How can I paint adopting the gradiant for brush-colors?
When using brush-dynamics random-color, it does use the gradient-color, but
not in the correct sequence.
It uses it in a random sequence! If you want to use the gradient in a
non-random way, define a new paint dynamics, and check a box in the
Color line of its Mapping matrix, for example Pressure or Direction.

3. Using brushes with a minimum distance of 1 lieves a gap using a brush
caligraphic-brush with an angle of 40%.
Don't understand what you're telling. What painting tool and what
exact brush are you using?

4. The mapping matrix for the dynamic settings of the bushes is not
editable. How can I edit this map to use on my own brushes?
You have to define a new paint dynamics. Use the second or third
button in the bottom of the Paint Dynamics dockable dialog.
These three points became clear, after I found the mapping-matrix. It was kind of hidden. This on one hand is a great feature, because you don't have to create a new set of brushes every time you want the brush to fade, scale or turn within one stroke. On the other hand it is quite complicating to use it espacially to new users.

One of my club-members asked me, why the dynamic Off - option is within the list of dynamic options. Mayby it would be a good idea to move the off-option directly on the Tool-Options.
6. The Gimp Tool Options  "Smooth stroke" and "Incremental" don't show any
affect on the stroke of any brush. Do they only effect brushes using a
Set the opacity of your brush to 50%, and try it with or without
"Incremental" to see what it means.

For "Smooth stroke" try the Paintbrush tool with the Block 01 brush,
set the options of Smoot stroke to their maximum, and try with or
without checking the option.
Ok, thanks, see the difference, now.

It would be great if you could give me a hint on what I do wrong.
Mayby it is a problem with my system (Xubuntu 12.4) I used the packages to
compile gimp, shortly after you annouced it.
Your distribution or installation is not important, but these features are new.
Oh, there are the odd one or two differences some times. Like on Windows you can edit any mapping-matrix. On my linux-system I can't. I can only edit selfmade dynamics. And Ubuntu is known to show difficulties with some programs.

Thanks in anyway.
