Killer-Feature request: Hide irrelevant parts on Website

[dnngll]

Hello,

I regularly use {find+} on looong websites like eBay (Results set to 200 per page of course). I just came to realize that it is always a bit of a pain to scroll over the parts of the page that I'm not interested. Wouldn't it be easier to just hide it? Please see my mockup (quick and dirty via mspaint):

Before:

After:

One would have to define, how many pixels above and below the search-result are shown. Plus the thickness/color/etc. of the separator (pink in my example).

Very curious about what you think.

Thanks!
