RfE: Auto-save should create a persistent Document

backup
auto-save

#1

by default and not a temporary document which is auto-wiped during regular shutdown of SketchUp, at least optionally.

Keeping the storage clean is a nice thing but having an Auto-save document if something unexpected happens is surely nicer.

btw, having a revision system lite by a configurable counter (“xxx.01.skp”) for the Auto-save and more important the BackUp documents would be neat too.


Sketchup crashed, I saved progress but 4 hours work lost :-( help!?
