Hmmm...
I don't think Lee has disappeared - just trying to have a life I would think.
We all take programs like AFCAD and TTools for granted and expect new versions to keep coming out for free every few weeks. But a tremendous amount of work is involved and it's unreasonable just to expect someone like Lee to spend what would be most of his waking hours on what started out as a labour of love but has become probably the two most wanted FS utilities ever in the history if flightsim.
We should think ourselves very lucky that Lee hasn't gone down the same road as Pete Dowson did - quite understandably - with FSUIPC, and also ActiveCamera
So my message is, be patient. If you are keen to start placing scenery objects now, take a look at some of the other systems available, starting manually using the XML Scenery SDK. I also just beta tested another new program which I don't think has been launched yet called Runway12. It's been made by a talented programmer and makes the placing of library objects a snip, so keep your eyes open for it.
