Sounds interesting! I would love to have the ability to have more custom rules. At the very least, it sounds like Bulle could be a potential candidate for helping on the Emu dev team
I believe the devs have been working to add more rules in the future. I read all of these posts, but I am not much of a coder, so I don't fully understand how hooks differ from the normal way that KLS, Wildcardx, FNW and the team have been adding new rules. To me, it seems like hooks are just another way to add more custom rules. I am not sure how the devs currently do it, but their way seems to work well. As long as everything works in the end code, I am happy though, lol.
