Would be wonderful if the Crafting Orders frame wouldn't auto close when you moved away from the NPC's so we can do things like open the AH / check the mailbox to get the items.

hi, I can look into it, as an optional feature, but I probably won't have time for a while
instead, you can use this macro to show the UI without having to talk to the NPC (keep in mind that you cannot create orders, or view your order history, without actually talking to the NPC; but you can see all the available recipes, and the search works fine)
/run ProfessionsCustomerOrders_LoadUI() ToggleFrame(ProfessionsCustomerOrdersFrame)

this macro is probably a lot nicer, than the frame not closing automatically 🙂
