Currently, yes and no.

pyspider is running original python code, something like portia is a code generator (Apologize if I'm wrong, I have not use it). So it can been made as another WebUI module.

But for flexible, I have no idea how to make it right currently. So, We have a css selector helper, but no plan for a complete tool.

I am not trying to offend you, but I really don't understand when someone says "yes and no". I hear it more and more these days. Is this becoming a cliche? It can be "yes" or "no", not both together. "yes and no" is "no" for me.

Don't know about other languages, but in german this phrase is pretty common when there is no clear yes or no answer. Like "yes to some extend but not completely"
