Decals on doors?!

Hi all  

What do you say about having decals on doors?

I mostly don't place any decals since it looks kind of silly with them hanging in thin air (I suppose most play with walls hidden but doors fully visible).
Also they usually hide some parts of the room of course.
Placing them on doors would make much more sense, and look much better.

What do the veterans in here say?
If many like the idea, maybe we can have it implemented.
Probably pretty simple to add I suppose, at least if we exclude doors with windows.
If it's a stupid idea, I suggest we forget about it

i've often wondered if it is possible that some doors actually feature decals.

Also, being able to put decals/numbers on the elevator would be really useful!
And very realistic!
You can't even put them on the side of the elevator doors for some reason

Would be a good addition in my book. Purely cosmetical, but nice.
