Thanks for the links.

I think you misunderstood my observation about Trim > they could all see and use it pretty easily when I showed it to them. I was making a comparison to Rhino> where there are so many tools (buttons) that they regularly can't find the one they are looking for by identifying the graphic/metaphor/label. By grouping the icons by function, and having far fewer of them, and probably having the context dialogs appear above the tool rather than in the command line, MOI is pretty easy to learn. That was what I meant to say there.
