First of all, I love the ability in 6.0 to grab 3D graphics and spin 
them around with the mouse. However, it would be nice if there were a 
more obvious way to return to the original ViewPoint and ViewVertical 
settings. Re-executing the graphic doesn't do it. I just now discovered 
that deleting the output cell before re-executing *does* return the 
graphic to the original ViewPoint / ViewVertical, but this (to me) 
wasn't an obvious thing to do. (I've had 6.0 for a good six or eight 
weeks, and I just now thought of it. Up until now I had been copying the 
input into a new cell and executing the new one, which I found a bit 
annoying.) OK, deleting the output before re-executing does work, but 
it's an extra step that I don't think should be necessary.

Also, after rotating a graphic with the mouse, it would be nice to have 
an easy way to save a copy of the input for the graphic with the current 
ViewPoint (and ViewVertical) settings. Right now the only way I can see 
to extract the ViewPoint (and ViewVertical) is to open up the output 
cell (Shft-Ctrl-E), scroll all the way to the end, copy the ViewPoint 
and ViewVertical, close up the cell, and paste the ViewPoint and 
ViewVertical into my input. This isn't something I'd ever suggest to my 
students.

So here's what I would really like.

1. Re-executing a 3D graphic would return it to the original ViewPoint 
and ViewVertical settings.

2. An easy way to make a copy of a graphic with the current ViewPoint 
and ViewVertical settings pasted into the input, sort of like the way 
Paste Snapshot works for Manipulate, so that I can delete all output 
before quitting, come back later and recreate the graphic in the state 
that I had it.

(With regard to #2, my students have limited storage space on the 
network, and it also makes the files smaller for passing them around via 
e-mail or web if we can save them with output deleted.)
