One of the things that I really like about Safari is that it allows you to access the full history using the menubar. Most browsers that I have seen only show the last 10 or 20 history items in the menubar, including Orion. I tend to use the history very frequently to navigate to webpages and it's very nice to be able to go up to history and find anything that I've looked at throughout the day. I understand that showing the entire history in the menubar is impractical and best left to the history window, but showing everything from the last week would be nice.
To avoid the history menu from being extremely long Safari will show everything from today, and then groups the history by day for the previous days:
