Using drag and drop outside the heirarchy

Hi there,

I have some data objects set up as GameObjects within the scene in order to manually set references between objects within the editor. I like this functionality, but it’s starting to become unwieldy to have such a complicated structure within the scene that really has no reason to be there.

I’d like to be able to use a drag and drop style GUI to replicate this functionality in an editor window or inspector. Would this be possible?

Generally speaking, it would be nice to extend the Heirarchy and Project views or include one (or two) in another Editor Window. Could this someday be possible?
