I have reported before about the usefulness and visual benefit of "aligning" boxes on different pages.
In RC3, I noticed that the space below the bar that shows up AFTER performing a search is close to the word Search, see attached.
It would be better IMO to also align this spacing with ALL the others, as Categories, Tags, Users and Badges have the same "spacing strategy", but not this one.
It will create a little more white space but would be more consistent in the way of standard layout.
When users have multiple tabs open to do different things, this will add to the premium feel of carefully designed software with attention to detail.
Thanks
