"A request on the Ionic Forum came in asking if you could have a badge on an icon in a list. Ionic’s Tab directive allows for a badge to be added on an icon. When we are talking about a badge, we’re talking about the little number in a circle usually on the top right corner of an icon. It is usually used to signify an alert or notification.
So, to accomplish this with a list with icons to the left, we can reuse some of Ionic’s CSS with one minor change."
