Hey, here's some forum posts you should look at and support!
Art Competitions (thread started by KittyKitty)
"Back on Horse Isle 2 the game would have a Art Competition set, Like a theme would be chosen and you would enter a entry, players would vote on it etc. I was hoping that HI3 could add that? I think it'd be really fun!"
SUGGESTION: Sorting Mail (thread started by MoonFang) "As I'm sure most players who have been playing for a while know, Mail can pile up! I'd love to be able to sort my mail by more than just the default (oldest mail first). In addition to the default, I'd like to be able to sort by newest, player name (alphabetical and reverse alphabetical), and subject (alphabetical and reverse alphabetical)."
SUGGESTION: Barber option to flip horse mane (thread started by MoonFang)
"Many players love having long manes on their horses, but these long manes can make it difficult to see the horses pretty coat. This is particularly frustrating with certain mosi and pinto patterns. Fortunately, HI3 has some very talented horse barbers. I would love for the barber to be able to flip horses manes to the offside. It would be especially cool if all mane options could be mirrored to the other side. If this were available for all/most manes, then the option to flip the mane could fit nicely as a toggle on the barber's preview page."
