Gmail Labs adds a new Multiple Inboxes feature today that allows you to keep an eye on multiple buckets at once while you're viewing your inbox. Just head to the Labs tab in your Gmail account to enable the new feature. Once enabled, you'll get a new Multiple inboxes tab in your Gmail settings. From there, you can choose up to five different panes to display to the right of your Gmail inbox, above your inbox, or below it. For label and filter junkies, the Multiple Inboxes feature is a must.
