With iGoogle, you can personalize your homepage with the information on the web that's most useful and relevant to you. Because the Gmail gadget has to share space with other gadgets on the screen, the Gmail experience can be limited to an area not much larger than the size of a business card. In this matter, Google adapted Gmail for mobile version of iGoogle and rolled out an update to desktop gadget," announced Gmail blog.
The new gadget currently requires a WebKit compatible browser, such as Chrome or Safari.
"The new Gmail gadget is pretty similar to the mobile experience -- it's fast, looks good in small spaces, and includes popular features like search and labeling. By default, it appears in a minimized window (see pic below); if you expand it into canvas mode by clicking on the maximize button in the upper right hand corner, you get the two pane view until now provided only on tablet devices (pic 2 below)," Gmail blog explained.
Going forward, the Gmail gadget will be updated with new features in tandem with the mobile edition.
Google said, the Gmail gadet will roll out over the next couple weeks. If you're already using the gadget, it will update automatically. If you're not, you can add it to your iGoogle page here.
