Manually "paint-select" mesh faces - How?

Wow @clement, This is just perfect and it does exactly what I want…

Somehow I didn’t see your post earlier, I only saw it now (sorry for that) when I was planning for a new post on the subject.

It would be great if I could provide or initiate a command like thi from my GH definition so that the end user of my intended GH plugin wouldn’t have to install multiple plugins. Any hints on that?
