If you add collapsing, make it optional only
 

Many people have asked for the ad blocker to "collapse" the white space left where ads were.

If this ever gets added, please keep it OPTIONAL, as an ad blocking preference.

I, for one, use OW at work primarily [b]because[/b] it shows where the ads were. I need to know the intended layout of people's pages, except I hate looking at the ads. This way, I see where they would have been, and can turn the ads on if I need to see the full site design.

Thanks.

Same here. Plus I have ad blocking really tightened down so seeing the placeholders helps me see that an image is missing that shouldn't be.
