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.

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.

Ok, thanks, see the difference, now.

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.
