If you often send emails to multiple recipients, a new feature in Gmail Labs will now help you to ensure that you don’t inadvertently forget a recipient you typically include in your group emails. After you activate it, this new feature, “Suggest more Recipients,” kicks in after you add at least two recipients to your message. If you, for example, usually send out a message to your mom, dad, sister and brother together, Gmail will suggest that you add both your sister and brother to the list of recipients after you type in your mother’s and father’s address.
In our short tests, the suggestions turned out to be quite useful, and we assume that Gmail will learn to detect more groups over time.
At this point, Gmail Labs features close to 50 ‘experiments,’ and Google is clearly making good use of Gmail Labs to incubate interesting new features. Some, like Superstars, Search Autocomplete, Inserting Images, or Custom Label Colors should really become part of the default Gmail experience, but in typical Google fashion, it always takes a while before any new feature graduates from beta status.
Of course, Google also wants to keep the default Gmail experience basic, so some of these Labs features might never become part of the default interface.
