I think it would be nice to have the terrain editor as a separate option just like the ebe once you have created your terrain then place it in the main viewport,
this would give us a drastic speed boost, we would only create what we need for our levels.
I think it is time to think about de-coupling the terrain maybe with an advanced option so that new users can continue with what we have but the more experienced able to create whatever size type of terrain they actually need if any.
I'm sure it would be very easy to de-couple it from the main editor window and have it as a separate option.
