+### Minimizing Function Footprint
+It's good practice when writing plugins to only take up one slot within $.fn. This reduces both the chance that your plugin will be overridden, and the chance that your plugin will override other plugins. In other words, this is bad:
+```javascript
+(function( $ ) {
+    $.fn.openPopup = function() {
+        // Open popup code.
+    };
+    $.fn.closePopup = function() {
+        // Close popup code.
+    };
+}( jQuery ));
+```
+It would be much better to have one slot, and use parameters to control what action that one slot performs.
+```javascript
+(function( $ ) {
+    $.fn.popup = function( action ) {
+        if ( action === "open") {
+            // Open popup code.
+        }
+        if ( action === "close" ) {
+            // Close popup code.
+        }
+    };
+}( jQuery ));
+```
