tedster - Thanks for that. That's a very handy tool to have back again. Those serps also display numbers, which are very useful for reference.
I just played around with it a little. While I generally search plain vanilla google.com at the default of 10 results, I like the ie output to show 100... so I combined parameters...
Once you're in the "ie" interface at a given number of results, that interface seems to hold the old ie?q=&num=100 settings and you can use it for other searches.
A search for more info about the google output parameter, btw, leads to this, which doesn't mention "ie"...

The output parameter may be fertile ground for other useful display options.
