You should add some kind of minimap plugin, also, if you could put breeding in the mcstats, that'd be really cool too!
1. you could just install a minimap mod.
2. I think there's already a breeding stat but i haven't checked in a while.
You can't install Minimap plugins, As the server cannot modify what your client sees. The only way to do it is via installing a client mod (Or with something like Spout... but that's pretty much the same as installing a client mod)
