I haven't been doing much modding over the last couple weeks because I've been working on this instead:
It's a fully-functional user-defined language for Notepad++. It has syntax highlighting and auto-completion based on all the terms found in nwscript.nss. I've done all my coding over the last ten years with Notepad - the regular one - with none of these features, so I think it's pretty cool to have now.
(The code I typed is garbage, though. I was just putting stuff down to show a few of the features and I forgot to assign the command to an object.)
