Hello,
I would like to ask if there are any mods that use 'Improved animation support' feature of Morrowind Code Patch. The reason I'm asking this is because most player animation mods say in readme they are not compatible with this feature. However I have never seen a mod that would actually require this feature. So perhaps a better question would be whether there is any reason to actually install this feature in MCP?

Oblivion spell casting does not use this feature, it uses MWSE and MWE and the only thing it does is that it allows casting with weapon, which MCP now offers by itself.
