Glims for Safari is a input-manager hack (I think) that enables a few ‘nice to have’ features. First, it adds favicons to tabs. I am not sure about you, but the new tabs (when you have a lot of them) are really hard to tell one from another. This helps. It also does things like add thumbnails to search results and makes the search history/recommendations look like Inquisitor a bit.
I might give this a spin.
