Yes, we are working on a tutorial.
I'd prefer to do something in, say - flash, as part of the website, but people aren't likely to start there.
So I'm part-way through a design for a change in the client that would function as an in-line tutorial.
I've got a few areas that make use of the flyover messages, but they are not everywhere.
We will intend to have much more content before we initiate the monthly charge.
As for the interface - yes, there is a lot there. I've only got a few more areas that are coded with XYLayout. Once those are converted, then I can turn off the size lock. Ultimately, I intend to convert to a more 3D look, with overlays and controls that are only visible when available. But I'm not a 3D programmer, and they don't grow on trees.
Thanks for your insight.
