I would like to see a Notes section on an owned Horse.
This would allow breeders to leave a note on any horse they own, in order to keep track of their plans for that horse. We are able to build up a lot of them in our various stables, and it can become difficult to remember which horse you were planning to breed to another, and what your ideas were for the future, etc. A notes section would give us the in-game opportunity to track those plans more closely without having to resort to external programs or apps (something I'm not so great at).
A Notes section on horses, and perhaps some other things in-game that I'm not properly envisioning, would also provide an opportunity for anyone who likes to RP to write up biographies or histories for the horses they want to include in their interactions.
Of course the Notes section would need to be wiped clear any time a horse is sold. I shudder to think of the kinds of things some players might leave as notes on a horse that the next owner would unfortunately see.
I know this is not a big deal, but it would be a nice thing to see somewhere down the road, thanks.
