No reference viewer for level objects?
The reference viewer tool for uassets is extremely useful. But if you create a blueprint with an Actor Reference variable. Place the blueprint in the level... use the eye-dropper to reference another object in the level. Then later you try to delete the referenced object you get a low-information dialog. "Actor XYZ is referenced by another Actor, do you really want to delete it? For a big level with multiple developers this can be a problem. At a minimum that dialog should give you the name(s)/count of the actors with references so you can investigate and see what you might be breaking. Ideally right clicking on an actor in the level would use the same Reference Viewer interface to show you the relationships.

Chiming in to say that I'd also like to see better built-in tools to handle this kind of problem.
The only solution I've been able to find is to export the level to text (File->Export-> Select .t3d as export format). Now if you open up the .t3d map file you can manually search the level for references to specific assets. Manually search for the name of a given actor you'd like to move. You should find all the references eventually, but the process is not pleasant. As always, save beforehand, double check your work, and even keep a document if you have a particularly deep or intertwined network.
Obviously this is not an ideal workflow and the editor GUI should be both showing you other actors with references in the deletion confirmation dialog, as well as showing these references in the sadly lacking "Reference Viewer." However if you really need to track down a reference and have no other solution, the approach I mentioned should work.
