I didn’t know quite what to call this group of items, but they are all used to bind/stick/group stationary together. Each item has a “normal” and “used” state which can be used for your web interface or next mockup. All ojbects are created using smart objects and vector masks so scaling is a breeze!
The corkboard view shows an example of each object in use. You can also view my “Web Lists” item to see other examples of uses.
