Comment (by valombre):

 Ok it has been a while since I request that feature and it has not been
 implemented yet so i will tempt again with a more constructive post :)

 If you would just like ideas, i have some for you. As you refused my
 request for esthetic purpose, I suppose you'd like a discrete
 implementation :

 You could then just not display a message, but use tabs-colors. I saw such
 an implementation in Sameplace [http://sameplace.cc/] and it looks rather
 well.

 Another solution, and maybe simpler for you, would be to replace the old
 typing icon you used in the previous releases of pidgin by others
 chatstates icons. This icon would change with the chatstate.

 Thanks for thinking of it and maybe working on it.
