I'm just going to provide some of the information needed to script your own window for that. Health and Exp I'm not really use to yet to call it properly.
Pokemon Icon displaying:
#Can pretty much just be any number.
* Has to be from 0-5, 0 being team number 1, 5 being team number 6.
@pkmn1.x= X co-ordinates
@pkmn1.y= Y co-ordinates
@pkmn1.z= Layer of which the sprite is on, (common number of 9999)
If you want them to be animated add in @pkmn1.update. Remember this just updates that one sprite, needs to be done for all 6 calls.
This is just some of the functions to get you started off.
