Safari history tip
I've been noticing for a while that pages that I click on in my Google search results don't show up in the history like I expect them to. Rather than showing the titles of the pages they display as Google URLs instead - not particularly useful if you want to retrace your steps.
A quick search turned up this discussion on Apple's support site where it's mentioned that this is a side-effect of Google's Instant feature. If you'd rather have history entries than the ability to see results as you type, you can select the "Never show Instant results" option on your Search Settings page.
