Why does GS2 not function with the current offline editor?

[Raeiphon]

I left a year ago expecting such features when I came back.

It's the same as it was when I left. Whatever happened to GS2 support for the offline level editor? It's goddamn impossible to practice GS2 in an environment where you're unable to compile a script to test it's effect and see the results

Maybe you crazy people are used to learning like that. I'm standing resolute by my belief that half of you are robots.

Enlighten me - why is this so?
