I notice after upgrading to RC4 today and seeing the new styled search box in header area, that it isn't really Vertical Aligned with equal spacing below and above it (to match logo on left being Vertical Aligned centre). I looked in forms.css at code for it and did this.

Change: 30px for margin-top - to 24px instead. That will Vertical Align the new search box (29px below and above it). Looks better and matches logo being vertical aligned in header area.

.search-header

{ border-radius: 4px; display: block; float: right; margin-right: 5px; margin-top: 24px; }
