Hi Nathan,
I really enjoy experimenting with Cycles and looking forward to the development into a productive tool. It is amazing already, but some minor issues keep costing my setup time. Hope this could be fixed relatively easy 
Quick bug report: Settings of the display mode are not remembered across rhino sessions.
I always have to do the following in the display panel after starting Rhino:
- Background: set to “solid color” (goes back to “Use render settings”)
- Check “Surface Edges” (goes back to unchecked)
- Go to “Raytraced Settings” in Options dialog, and set “Use single color for all edges” under Objects/Surface
Would be great if Cycles remembered those (and all other) user settings.
Cheers, Frank
