In late 2007, Wikipedia added a new, eleventh tab to the My Preferences page—the Gadgets tab. Since then, about 20 gadgets (as of this writing) have been included in the tab, as shown in Figure 20-14. The Gadgets tab lets you quickly implement JavaScript user scripts and/or CSS code developed by other editors to add cool new features to Wikipedia.

Figure 20-14. As of this writing, the Gadgets tab includes about twenty JavaScript and/or CSS code chunks (not all shown) that can be enabled simply by checking a box.

Chapter 21 (Adding a Script) describes how to implement JavaScript user scripts by copying them to a page in your userspace. Using the Gadgets tab is much easier; just select a gadget, and then click Save. Then, as the instructions at the bottom of the tab say, bypass your browser cache to see the gadget’s effects.

Currently, you can implement user scripts either by choosing them on the Gadgets tab, or by using the more complex process described in Chapter 21. The advantage of the do-it-yourself approach is that it works for any user script, not just the currently limited number available on the Gadgets tab.

You can get more information about each item on the Gadgets tab by looking at the Special:Gadgets page.
