I can't find anything on this but I really suspect it already exists.
My users want to be able to pick up an object from my TreeCtrl and drop it into another instance of my software. The items in my TreeCtrl are all serializable and can already be transferred from one instance to another by writing to file, but D&D would be very slick. However, they don't exist outside the software at the time when the D&D is done.
Is this already possible in UPP or would it be a new feature?

It is already possible. You will have to implement some data format to store what you want to d&d for doing that...
