But for the common case of wanting to teleport a Morph from one project to another we can make a nice clean abstraction. Like maybe
Project chooseNewProjectAndMoveMorph: self
This makes it convenient for Project to use the appropriate UI as for opening browsers etc and hides possible different arrangements for the way morphs might live in the new project. After all, a new kind of project might now have a world concept; we shouldn't know or care at this point.
Perhaps return the destination Project or nil so we can do something further if the user chose to cancel or the project declined to accept the transfer. Again, send something like #acceptTransferOfMorph: theMorph to the chosen Project.
