Gate exemption

[Wackmo]

Hello!
I'm having trouble getting pictures into this thread, because my computer won't let me access my screenshots, but hopefully you'll get what I am talking about.

One of my favorite little additions on the server is the [gate] thing that you can put on a sign and cause fences to lift in a gate-like way. However, I've been a but perturbed by this command causing other fences that are not meant to be part of the gate to lift up. For example, the windows in my horse barn are made of fences, and the windows lift every time i right click the sign along with the gate. I know that I could just move the real gate and stuff, or activate it using redstone, but I know other people have been annoyed by the same thing, and I think this could be an easy solve(although I'm no modder).

Could we have a command, similar to /lock (where you punch to add wg protection to signs), to fences where you could exempt them from being lifted by [gate] signs? Its quite simple but I think would be a nice little addition to the server.

Or it could just be me. :/

Thanks!
Wack
