My suggestions in no particular order:
1) Would love to see 'edit special abilities' included in the GUI.
2) Would be positively head-over-heels for a subtle visual cue (in the 2D engine) for big hits.
3) Would greatly appreciate an improvement in 2D goalie tracking, (so goalies don't remain stationary while the opposition wins the faceoff back to the point - fires a quick cross ice pass to the other point - and shoots into an empty net).
I know the holidays are over, but this little wish list would certainly bring them back for me!
