I like doing vigilante missions but it drives me nuts when you are shooting at a gang of armed folk and the police come in and decided you are the biggest threat.
So, if anyone is looking for a little project, a mod that disabled the police when you are on vigilante missions would be great.
Or getting a bit more complicated, a mod that disabled the police coming after you for shooting the marked bad guys. But they still come after you for shooting peds or cops.
EDIT: Balls, just noticed there is a pinned topic for requests. Sorry.
