From @NickCraver

I like the new @NuGet layout, but not the copious amounts of whitespace. Here are search results with that toned down (vs. current):

Suggestion:

Another optimization here is making sure the heading of the package title/ID has the same top baseline as the image. Right now, it looks like the heading is a little lower than the image.

There's a related alignment issue:
Note that the results are slightly wider than the rest of the page due to the negative margins in .row here:

.row {
    margin-right: -15px;
    margin-left: -15px;
}

Improved. Not yet deployed. Will keep an eye on further feedback.
