Stabled horses should be identified by name if named, rather than level especially if two horses are the same level. Currently my named horses display only level in the stable (Edit: It's the renaming issue as I now have some named horses in the stable but it doesn't display in the pet window.).. Also when I get the horse back it should be fully fed.. I mean I did pay the Equerry a silver! Also there is a bug which I reported concerning renaming a pets. They are also still floating beneath ground level on hills often. One more stupid thing is they should make more noise generally (they're a big part of the game imo).
