Its not an editor, you are right.:)
When I reply to you I see a small icon beside the "html" one, that says "insert code block". When I open that to paste in some code, I always have to select "javascript" manually, although it should already know that I am not going to post c# code. Maybe
one could introduce a little tag for each forum that deals with programming languages and then the "editor" could select a reasonable default.
