Saving your browsing session!
I often leave my web browser open just because I have some web pages open that I want to check out later. Bookmarking them one by one is not really an option. There is a way to save what is open in bulk.
1. In Safari 3.0, go to "Bookmarks" and choose "Add Bookmark For These 3 Tabs...".
2. Name the bookmark and save it. It will create a folder with a bookmark for each tab that you have open. If you later want to reopen them all at once, click on the bookmark folder and choose "Open in tabs".
