Infos about current client customizations

[nibbio]

Hi all!
I'm an old developer and I'm trying to understand the current situation of CC and EC client customization support.
Currently I wish to know these informations for both clients:

• Custom maps
• Custom statics
• Custom animations (addition and replace)
• Paperdoll addition and modifications
• Custom multis

I tried to search through various forums but seems that Noone has made further steps about those points.

My idea is to know how much the current clients are customizable and how much support can come from the community. Malganis and Kons seems to be out of this game.

Thanks for the answers!
