- ctrl-click an item to try it on: the dressing room dresses your double, and shift-click posts the item link to chat - the pet tab lands in the character window: paper doll stats, family and diet, the right-click menu, and dropping food on the pet feeds it - water-only spells refuse on dry land: aquatic form gates to swimming, client-side like the real one - the macro icon picker's white squares get their art back, and option rows explain themselves on hover Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
