Just as the title says, can we get a functionality that sends our unused characters into training horses (Example, choose X character (Pro-Artisan training required) at stable, assign to Y Horse, start AFK training) in the stable? I think its long overdue that we require ways to use our alt characters at the same time as we use our main.

I just thought it would be dope to train 6 horses at the same time, to have them lvl 30 without having to consume much electricity or kill my computer minimized at tray (With the bugs it comes with, since afk horse training is currently so flawed it doesn't really make me wanna do it). Let's say it takes 48h of afk training for a T8 Horse to reach lvl 30, this function would take 7 days per character per horse and that seems fair to me since we're mostly all working class.

What do you think?

I don't see that happening. You can use your ALTs for energy and that's it. Then that energy you convert to energy pots, roll for workers or play the amity game/use knowledge objects while you get all knowledge you can use energy for.
