The 1 second delay is intentional.

Yes.

When you set the animation mode you can specify a delay of 0 at the
beginning and the end of the cycle.

animation mode palindrome 0 0
OR
animation mode loop 0 0

... whichever is appropriate

Yes, this should work today:

model {1, 2, 3, etc.}
vibration on

vibration scale 2.0
vector scale 4.0

I suppose so ... but there are so many file formats that I have forgotten
how to distinguish between them :-)
