Love this, though it's grovelling over my screw threads.

One thing, though. My desktop lost power during the final stage (after pressing 'enter'), and when I restarted Sketchup I chose to recover from the last autosave. Unfortunately, the shape-bending context didn't save gracefully (shape to bend had weird alterations, there were multiple 'start'/'end' markers, etc.) and I had to throw things out and re-load from the last manual save.

I don't know if SU provides a mechanism for plugins to be notified when a save is about to happen, but if so I think there's room for some fixes there.

How often do you lose power, though..
