OK, and the problem with the built-in Python Editor in Rhino is…? It has autocompletion for both rhinoscriptsyntax and RhinoCommon. Plus debugging if you are running the script inside Rhino.
@Helvetosaur Autocompletion works poorly. After working on a daily basis with Visual Studio, using the python editor in Rhino really gets to me… What I would really like to see is Visual Studio as the main editor for Python scripting. That would make a huge difference.
@xliotx Check out @Angel 's blog. He did a post a while back connecting an external editor to a GHPython Component.
The auto indent and de-indent, change multiple variables at once, auto-completion for code blocks, etc…
Also, better auto completion is needed, not only for buildin functions, but for everyting.
