We have introduced a new feature in today's build called stickers. Stickers are basically a collection of ready-made images that consists of buttons, widgets, seals and logos widely used in websites. For example in the above mockup of a shopping cart, you will find stickers of 'sign in with twitter', 'feedback' button, 'buy now' and some privacy seals. This gives you can idea about their uses and how they make things easier by letting you reuse commonly used stuff.You can find stickers in the newly re-designed image manager. Being a library of its own, we would expand it based on suggestions, so bring in your ideas.
