Currently Scribus doesn't have an "Inset/Outset" tool for polygons.
The existing "Scale" functions (e.g. in Transform and the Node Editor) work well for what they do but can't achieve the same results as the "Inset/Outset" functions in Inkscape (see image).
What do people think about requesting this additional functionality for Scribus?
How do you think it should work?
Where do you think it should be accessible from?
