Google made available the Gmail contextual gadgets API to all Google Apps Marketplace developers. “Now, you’ll be able to use our predefined email context extractors to contextually trigger your gadgets within Gmail. In the future, you’ll also be able to write custom context extractors. Contextual gadgets that you write can be bundled into manifests & listed on Apps Marketplace. Google Apps domain administrators can deploy your gadgets to their users with a few clicks. As with all new APIs, we’ll keep this one in Labs as we enhance these gadgets. Several apps featuring Gmail contextual gadgets are launching on Marketplace: AwayFind, Kwaga, Gist, Pixetell, Smartsheet, Xobni, Rapportive, Manymoon, Newmind Group, and BillFLO, with more on the way,” writes Google.
