It would definitely be nice to have those abilities... especially font, font color and font size. I've only done a few scripts that use those things because I don't like having to package a DLL with a small script just to make the script look nice. It just makes it too big for a small script. Of course, if everyone had the DCX and MDX DLL files already, then it wouldn't be a problem, but I don't like to rely on that.
Having it built in would be wonderful.
