Yes. Your script now:
lots of code
forever[ .. wait .. ]
Your code later
lots of code
view/new layout[ .. ]
forever[ .. wait .. ]
With view/new 'view does not block.
And 'wait has the event-processing inbuild, so when waiting events are
processed automatically. So gui stays alive.
The smarter way using port/awake i leave to others ;)
