Rocks'n'Diamonds

I have many hidden CEs and want to see them in editor marked. I know it's already possible when using graphicsinfo.conf, but that isn't enough sometimes. (E.g. when you're just testing the level in private levels etc.) I'd like some config option similar to "use graphics of element", but applies just to editor (something like "use graphics in editor"). The reasons for using it (instead of graphicsinfo.conf) are the same as the reasons for using option "use graphics of element".
(not a feature I need but an useful one anyway)

For now I think that "use graphics of" should do the job -- it also displays that changed graphic in the editor, which should be the thing that is wanted in most cases. (For other cases, like hiding elements in the editor, the graphicsinfo.conf file seems to be the best solution...)
