Ok, To those of you who want UV mapping, why? Its already embedded in. You can texture without it. Straight onto the model itself. I love this aspect of this and its the primary reason I use this tool. Seriously making UVs is a pain and i hate it. Discovering accidently that I didn't have to. That it would take a photorealistic image and paint it without distortion onto a face is an awesome thing. Yes, I understand about normals etc. That can be prepped outside of a 3d tool anyway. The sooner UV is shot in the head the better.
All the other wish items I see are ones that you all could get in Blender, zbrush and other tools. I don't need rigging nor animation. I have access to that in Blender.
What I do want to see is:

1. Selectable axis arrows like in Blender so I can click one and thats the only axis it moves on.
   2 a Move function that is isolated to move only. The bounding box turns into a a 3 ring sphere, click a ring and the component/model rotates only in that direction/axis. Move the copy and other functions elsewhere and kill the protractor. Move needs to be simple basic and not need a tutorial to relieve confusion and frustration.
   3.an interest function that actually intersects. The purpose of intersect is to merge two components together as one. That should be the default function. Highlight both components and them merge them together, intersect and bang, one component.
2. OBj import
3. stl export
   a match photo function that works with pictures shot from top down.
   (I can't helicopter shots because it makes steve look like he's falling into a black hole)
   I am happy this tool does have rigging or animation or other robust items. I don't feel It needs them.

Actually, The problems with Sketchup aren't the items you mentioned. In fact I do believe you are right. You gre out of Sketchup and should more on to zbrush, blender etc. All which have robust tools for bones, animation and rigging.
I don't need that.
What I actually want is intersect to actually intersect. Now five step bs. I want to take a component and shove it into another and they become one. Thats intersect. I want axis arrows on move so I can select the axis and move only in that direction (like Second life has. Its sad that a 10yr program has better 3d movement but they do). I want the protractor to die. I want the bounding box to turn into a sphere when you rotate and again select a axis and only rotates that way. I rotate to be ONLY rotate. Copy can go elsewhere. If I wanted to copy I would click copy.
These minor issues is what I think needs to be fixed.
