Yes I understood and you make it good, software have to have only one hiding system to not confuse user.
Last couple of days I'm learning Rhino, by this tutorial http://www.infiniteskills.com/training/learning-rhino-5.html and just finished this tutorial
Learned a lot of stuff.. Have to note I never know about curve from two points command and was very proud to find it in MOI (isect command).
I have to say you make GREATE job simplifying Rhino and grouping commands bravo!!!. I can not work in rhino after MOI because it too slow I mean a lot of commands it has and it takes a lot of time go through all that menus or typing. And great thing about moi is Boolean with curves! Super cool! And selecting ages and faces directly.
As I said you maid great JOB! Rhino is very powerful but it makes it very hulking.
