• Auto-suggest don't seem to work for queries with spaces. Am I missing something?
• If you select an item from the suggestion list that was matched by its title, the title is filled in before the address.
  • Can you change it to work like in other browsers?
  • SMRT disables searching by title completely.
• Can you combine Top Hit, History and Bookmarks into a single section?
  • The preferences starting with DebugSafari4 don't work anymore. (Like DebugSafari4IncludeFancyURLCompletionList.)
• Can you direct unresolved addresses to something like google.com/search?q=?&btnI instead of ?.com?
  • Like by changing keyword.URL in Firefox.
• Can you remove or hide the web search field?
  • In Camino, Cruz and Fluid it can be resized to zero width.
  • You can't circumvent the normal maximum ratio with InputFieldWidthRatio.
  • AddressBarIncludesGoogle doesn't appear do anything in the current version.

Are there fixes or workarounds to any of these? I'm lumping these issues together, because they are closely related — a lot of them were introduced when the location bar was redesigned in Safari 5. I'm also hoping to find something like an extension or a plugin that would replace the standard location bar.
