3 questions - texture-delay-control points

 From:  malvin
1 I would like to create some 3d texture file.
Is it possible to wrap the 3d texture around 3d pieces such as jewelry ring?
2 Offset and some other commands slow down and delay for a few seconds when carrying the pointer thru the field and everywhere it finds a snap it stops waits a few second then and stops on another snap. How to fix it?
3 When a curve is copied or offset the new curve create a lot many more control points than on the original one. Do I need to erase extra points by hand or there is a way to reduce the number of points automatically?
4. Shorcuts do not remain in the memory of the program except a few. How to make them to remain?
