One feature the editor MUST have

[JWJ]

The ability to make improvements and small wonders obsolete, like you can with great wonders. This is a glaring omission from the editor, and probably would be pretty easy to implement.

I agree. It doesn't seem that hard to do.

Nice and eassy idea

For me, this doesn't seems absolutely necessary, but it certainly seems like a useful feature that should be very easy to implement.

It would make sense that temples stopped creating a content face after monotheism was discovered, and there's certainly good use for it for scenario makers.
