Hi, I've just downloaded the 20070830 windows build of Inkscape and while playing with the tweak tool the first thing I wanted after using the roughen mode was a soften mode, something like a localized simplify path. The only problem I see with simplify path is that used after roughen leaves some disconnected nodes, like speckels. Anyway, great tool and excellent work yo're doing with Inkscape. Thanks for a great software.
According to Inkscape 0.45 release notes:
"We only support AI import and export for Adobe Illustrator 8.0 and older. This has been clarified in the Open and Save As lists"
The menu option does not appear under Windows.
I'm using inkscape 0.45.1
