Personally I didn't like B5 but it grew on me and now I love it as much as I loved any of the earlier versions. It's still not the powerhouse I wanted it to be but neither were the other ones, but at 200 bux it's a great deal. The only gripe I have is it's unstable sometimes when importing .3ds files of all things. Sometimes 3ds meshes will import completely in pieces and of different sizes. Other than that like deci6el says those questions you asked are in the manual and in the gui for the most part.
