An 'on DEBUG' event would be quite useful imho. Concidering that there is so much going on in that little @window it would be lovely to be able to distinguish things just a little more;
ie: by use of color for various numerics or even as simple as incoming and outgoing commands. The little -> and <- are helpful obviously (and more then sufficient as many would probably say) but the more options the better. This is by far the greatest scripting tool for debugging, a little enhancement to make the text more distinguable as stated above would be fantastic.
If not an 'on DEBUG' event, then perhaps a basic color field to distinguish -> <- commands.
ie:
/debug -pt 1 4 @raws
1 = black (incoming cmds)
4 = red (for outgoing cmds)
-pt = timestamp for those who are wondering
Cheers!
