[Inkscape-user] how to scale path nodes, not the object?

Hi all,

I'm used to Blender, enter edit mode and then have all the tools that apply to the entire object be available to any collection of selected vertices.

So question: how can I do the same in Inkscape?

What I want to do:

1 - F1 select path 2 - F2 select some nodes of the path 3 - scale/rotate those nodes relative to a specific center, or to the median point of the selected nodes.

At the moment, only grouped translation is possible as far as I can see.

Perhaps a python script would do? Is there a guide on how to script Inkscape with python?

Thanks in advance for any tips.

Albert
