I think "central aspects still under development" is a fair way to say it.
If you want to take a look, it is in the 'Experimental' folder. Feel 
free to ask questions.

Well, we have been evolving Morphic in Cuis, towards the direction shown 
by some experiments I did in 2009, for quite some time. This is 
currently using BitBltCanvas to draw, that can not do proper scalable 
graphics. The Morphic3Canvas in 'Experimental' can do this.

Morphic 3 is ready to be studied by really interested ones. Not at all 
ready for a naive- user. On the question of where this help is needed, 
I'm not the best to answer. Maybe others in the community answer this, 
or, just use the system for some project, and you'll quickly find the 
places where a new user (you!) could use better documentation.

Well, Morphic 3 might be more expensive than BitBltCanvas, and I don't 
know if it will run reasonably well on a Pi....
