Feature Request: Edit Instance similar to DM

[KathrinBailey]

Once I tried the new StrongDMM (it's awesome and saves a ton of time) I told Cinder that you can't actually delete instances, do you kind of have a big giant list. You can't edit instances either.
It'd be really awesome if we had the ability to edit instances (and delete them of course).

Would it also be possible to get something akin to mapdiffbot and render an image of the entire map and put it on your clipboard, or save it as a .png or something? It'd be helpful to be able to get high resolution images of large parts of the map.

To simplify progress tracking, I've decoupled the second part of the issue into a separate #31

In my opinion, this would make the StrongDMM map editor superior to every other DM-based map editor out there (Although it definitely already is)

P.S It's an absolutely amazing editor and it speeds up map creation SO much
