I have no argument with this. If we can do away with a separate dialogue 
altogether, so much the better.

I don't think it really needs to be that complicated. All we're talking about 
is 
the options already available in the export dialogue and 2 or more preview

Somewhere between 70 and 80 per cent is about normal for me, but on my latest 
project I've been getting good quality at as low as 60. You're probably right
