Steel should always be steel, even if it's behind terrain. Currently in discussion
here.

When terrain overlaps steel, allow the
terrain to be destroyed, "revealing" the steel underneath

When steel is
completely obscured by terrain, delete it (to help prevent "hidden steel" trolling)

Allow terrain pieces to be "steel-deleting" in the editor; such pieces will effectively re-shape the steel piece editor-side - this suggestion is currently in discussion
here.

Alternatively, always draw steel to a higher layer than terrain. Then, steel pieces would need to either be pre-decorated, or overlaid with "paint" objects - either way, this would be the best and only way to implement both "steel is always steel"
and "steel is steel wherever you can see it" in the same system![/list][/list]

If I ever get time, and a significant amount of help, we might be able to
restore .lvl compatibility to the Editor.
