Hi Nyall,
great that you dug out that old request!

In case that this button does all what I described as my workflow  
beforehand: Yes, thats what I'm after.
Alternatively, could there be maybe a checkbox at the Atlas generation tab  
or in the "Controlled by atlas"-part which sets this behavior permanently?  
This would even reduce the work to just switching the Atlas preview item.
Or as I said before, a switch like in georeferencer to sync the canvas to  
the composer extend ...

Anyway, great improvement so far.

Cheers
Bernd
