I got an enchant and it just listed that I tipped the guy. It'd be good to include the enchant. A lot of times enchants misfire and it's nice to have a confirmation in chat it worked.

You can take the code from GogoLoot for enchants and lockpicks if you want.

It's a loot add-on, which makes this very low-prio for me, but if I have some downtime in between I can add it

If you have trade announce, it should include everything traded.
