I'd really like to see some improvements to the base companions... like
NOT firing at the enemy till you do.
NOT chasing the enemy unless on FAR follow.


Rex not attacking people with Hats (makes him very hard to use)

Maybe included with some known bug fixes..
Boone getting stuck in interrogation room.
NCR not killing ED-E at the Fort..randomly.
etc.. I've only seen those 2 so far

Also,

Open the orders menu by using a key instead of talking with them.

thank you,

Finish his quest and he'll stop attacking people wearing hats.

This is in development, it may be far enough along to work for what you need though. Just understand as a young WIPz it sees frequent-ish updates.
