Quick Jump search icon shifts horizontally due to in/out traffic changes (7.1)

## What?

The Quick Jump search icon (i.e. the magnifying glass) should stay in a fixed position.

(**edit:** I guess this could be considered a bug more than a feature request-- just super minor)

## Why?

The Quick Jump search icon (i.e. the magnifying glass) slightly shifts horizontally as the in/out numbers change (e.g. `12/34` --> `5678/9012` pushes the icon to the left).

Maybe it could just be moved to the right of the in/out traffic details.
