About this cut-away view tool, it helps to use wireframe view and disabling front selecting. About the not mirror paint, I'll agree, bout about the more colors I don't know. Maybe if it is not difficult. But just we must not forget that A L L T H E S E was done ( and still continue to be done ) by one person
. And even the most simple and minor addition requires a lot of new code and in most cases even modifications to the already existing. I think the M_O_S_T important is to speed up ART renderer
. Untill now everybody was modelling with some tricks and stuff, but the only thing that you can't "trick" is the render time
. So I think first of all the most important request must be the speed of the renderer ( ART particularly ), even if no other addition whould be added. So, if Steve could do that, then if it's not too difficult, he can add some other stuff ( mirror bone command in figure mode whould be very usefull ).
