I made history search disappear somehow…
 

Being able to search through history is one of OmniWeb's sweetest features, but I broke it somehow. If I select "Show History" from the "History" menu, I see the Bookmarks window, but there's no longer a History option in the "Collections" list. Does anyone have any ideas on how I can get it back?

Quit OmniWeb.
Open a finder window and locate this file:

~/Library/Application Support/OmniWeb 5/Groups.plist

Remove it and relaunch OmniWeb.

That seemed to do it. Thanks!
