Hooks on the stall fence from which a bag of food can be hung. At least one pitchfork for distributing hay and one shovel for cleaning up manure. Hooks on the walls with harness hanging from them. Saddle blankets, saddle bags. Rope. Tools likely to be found in a stable: hoof knives, small hammers and nails for horseshoes, large brushes for currying, leatherworking tools—awls, big needles, spools of sinew, very large shears, knives, jars of oil. A large barrel full of feed; the horses probably graze for much of their diet, but they'll likely get a spadeful of oats on a regular basis. A spade. This appears to be a riding stable—no indication of a wagon or plow, so probably sugar or a small barrel of apples; people like to pamper their riding horses.

I think there would probably be stools near the worktables, also. Most of the grooms' time would be spent there rather than near the stalls. I am assuming that you've left off gates on the stalls and entrances in order to accommodate VTT users?
