Hrm. I hate to be a pessimist, but maybe they did not further enable the plant editor because it is not in their financial best interest to do so. It will not sell significantly more copies of Vue than will already be sold, and it WILL enable more people to get into the plant market.... and become direct competition to e-on.

We all want something beautiful
Man, I wish I was beautiful
When everybody loves me, I will never be lonely
