heh I missed this post... so yeah, I'll add my tidbit:
The ability to have the smilies panel open up after beginning a smiley. I haven't memorized all the codes for the smilies I use the most because I always use the panel, so it's much more effort to have to switch back to the mouse... I liked just typing the '(' and select the smiley. Why was this feature removed? Hopefully we'll see it back in the next update...
When I upgraded to Messenger Live with no MSG Plus, I put up with it knowing it would come back with the new Plus Live
