I hope that I am not out of place adding my thoughts on the UI. I started using CAD/CAM almost thirty years ago, when my father was an early developer of training programs. I am an accomplished draftsman, but, I can go for long periods without using a program (I still use hand drawing a lot), and find I need to reacquaint myself with the UI. JiHO, I think has a very good idea, with the ability to select from user profiles. Bulia's ideas about templates are also very excellent, I wish I was able to work on that one, but I can't. 
This may be out of place, but, my 'best of wish' would be specific to Mac; I would love to see a multiple user profiles (prewritten and customised) along with a start-up script available from a dashboard widget.
