Hello list again,
I sent my patch to Alexandre P. for him to commit it. It's a na´ve implementation for the low hanging https://bugs.launchpad.net/inkscape/+bug/171255 .
It's really nothing but I like the calligraphic tool a lot better with this small adjustment:
I added 4 icons for dip, pen, brush and reed in the toolbox with hard coded matching settings. Clicking one button sets the calligraphic tool with the matching presets.
I also removed the reset button (the default settings are the dip settings)
On the negative side, the toolbox gets very very long, and there is no way to customize those presets, but I think those are quite sane.
If you want to suggest more presets, ore some improvements, or your disagreements, please go.
