Totally agree with DarkAcreDan on what he posted. In addition to what he stated, when everything is left aligned, the icons crowd the edges, as seen below.

For illustration, the image shows two fences side by side with the same coloring. The red arrow points to the edges of each where they meet, and as can be seen, the 438 Solutions icon is not centered and is crowding the left edge of the Fence.

Being able to change the padding of the fences would suffice to solve the issue. But the best option is still to use centering, as that would automatically achieve the same result when the fence width was made wider, with equal, or near equal, spacing on the left and right sides.
