 <h3>Smart Rendering</h3>
 <p>With smart rendering, Android Studio displays links for quick fixes to rendering errors.
 For example, if you add a button to the layout without specifying the <em>width</em> and
-<em>height</em> atttributes, Android Studio displays the rendering message <em>Automatically
-add all missing attributs</em>. Clicking the message adds the missing attributes to the layout.</p>

+<h3>Annotations</h3>
+<p>Android Studio provides coding assistance for using annotations from the
+{@link android.support.annotation Support-Annotations} library, part of the
+Support Repository.
+
+Adding a dependency for this library enables you to decorate your code with annotations to help
+catch bugs, such as null pointer exceptions and resource type conflicts. You can also create
+enumerated annotations to, for example, check that a passed parameter value matches a value from
+a defined set of constants. For more information, see
+<a href="{@docRoot}tools/debugging/annotations.html#annotations">Improving Code Inspection with
+Annotations</a>.

+<h3>Java class decompiling</h3>
+<p>Android Studio allows you to look at what’s inside Java libraries when you don’t have access
+to the source code. </p>

+a class, method, or field from a library for which you do not have source file access and select

+<h3>Debugging and performance enhancements</h3>
+<p>Android Studio offers debugging and performance enhancements such as:</p>
+<ul>
+  <li>Auto detect an expanded set of code styles. To modify the current code style, choose
+   <strong>File &gt; Settings &gt; Code Styles</strong>.  </li>
+  <li>Support for high density (Retina) displays on Windows and Linux.  </li>
+  <li>Scratch files for quick prototyping without creating any project files.
+   <p>Choose <strong>Tools &gt; New Scratch File</strong> to open a scratch file to quickly
+   build and run code prototypes. Together with Android Studio coding assistance, scratch
+   files allow you to quickly run and debug code updates with the support of all file operations.
+   By embedding code created with scripting languages, you can run your code from within the
+   scratch file.</p>
