Some features

A way for weapons to deal damage to the wielder: AKA - Vicious. I dont know how to duplicate the effect outside of assigning damage to the PC, this bogs down in process when I have 7 PCs, 5 of which use vicious and some dual wield. Especially at higher levels - the less I need to monitor the faster the rounds can go.
An option to place negative levels on a Player. It's possible to make a buff perform for this task, but still a blanket option would be ideal.
The ability to drop an item on the ground, and move it into another character's inventory without needing to re-create the item or pull it from a list. This way PCs can feel like they actually pick up an item too, and it's less for me to have to manage. I can just drop things on the ground and they can grab them.
-This would also be ideal for making containers that can actually hold items - so the PCs can manage treasure chests themselves as well - or trade items amongst one another.

I'll edit in more ideas as time permits, im currently in the process of finishing off the MM1 for 3.5.
