One of my mobile mantras — No. 4, actually — is to turn off wireless radios and work offline when I can. Solutions like Google’s (s goog) Gears allows for that approach, but sometimes you don’t need your entire mailbox with you when you’re offline. Starting today, you get a little more control.
Google has now implemented a way to choose which mail you want to use offline with Gmail. Now you can tell Gears to only pull down mail from specific labels and from certain time periods. Only want your Inbox and two other labels from the past week? No problem. Once you have Gmail setup for offline use, just hit the Offline tab in Settings to pick and choose.
