I'm in the same boat as you as I've found PnP to be the most feature complete but non-obtrusive script out there, but it is showing its age. I'm thinking of eventually just going back to plain old mirc now that I'm on a network that really doesn't need all the protection/user-management settings, and the rest is just fluff. However, NNScript seems to show promise, and the latest 4.0 looks interesting, but it's intended more for the online PC gamer crowd so you might find it bloated for your needs. You can check it out at
