As far as I know [tag:omnibar]  relates either to the [Safari Omnibar][1] or to the Google Chrome omnibar / omnibox.  

As for the Safari Omnibar, it's basically a tweaked location bar (`"Search directly using location bar"`), and [tag:location-bar] is a synonym of [tag:address-bar].
  
As for the Google omnibar / omnibox, [even Google calls it "address bar"][2] so no need to refer to it as "omnibar".

22 out of the 23 questions tagged with [tag:omnibar] relate to the Google Chrome address bar, and only 1 relates to the Safari one.

Can [tag:omnibar] be merged into [tag:address-bar] and be a tag synonym of [tag:address-bar]?
