For those of you who use gmail, I'd recommend you try the 'new look' they're touting. It gives you new button formats (again...) but that's the worst part. The best is really very good, including:
- New format for conversations - so you can see more of each email on one page without expanding all and losing the thread.
- New search dropdown which gives you the advanced search features in a dropdown.
- Density control - less phenomenal but I really like it - allows you to control the density of email on the page.
For anyone who's avoided gmail based on the fact that it's free and not branded in your company name - give it a try. You can connect it to your company domain, and there's a paid version called Google Apps.
