I'll be interested in answers to this one as well as I like slippery footing and difficult terrain from corpse build up as well.
I had been using circular pointers in some of my sessions then deleting the combat record but its a pain.
I have just tried following
Creature is dead.
You click on the stats link on the RH side of combat tracker for that creature to open the creatures stats.
Drag the icon from the stat block on top of the token on the map then delete the combat tracker record.
It will leave behind the token you dropped in that location.
If you use blood effects they will be gone though.
Only other method would be to set them to not visible in combat tracker and set skip hidden actor on in the options.
But set the token visibility on map to always visible.
Anyone with other better ideas????
