What do you want to see on the site?

big mummy smeear i dont think anyone has said but

links that open in a new window!

simple and stops having to right click

is that just fussy and lazy of me though?

This is in the "Vanilla makes this difficult" bucket. If I changed it, it would be for all links everywhere and you'd have hundreds of windows to deal with.

Ideally it would be for external links only, and a user preference. But Vanilla doesn't readily offer a way to do that, each extension has to be built from scratch with nothing that gives you a head start.
