</ul>
<p><h2>Databindings</h2></p>
<ul>
  <li>API no longer provisional in 3.3</li>
  <li> Listeners are an overly complex way for widgets to interact</li>
  <li> Databindings are a way to connect widgets and model objects</li>
  <li> Reduces the amount of code required to synchronize data from the widget 
    to the model and vice versa</li>
  <li> Also handles conversion of data types and validation</li>
</ul>
<p><h2>Menus</h2></p>
<ul>
  <li> Actions were limited as to how you could add them</li>
  <li> The additions path was the only place to add an action</li>
  <li> Could not place a new entry anywhere you wanted</li>
  <li> Menus define the commands that will show up in them</li>
  <li> Menus allow you to do much more powerful enablement</li>
  <li> Everything is declarative so you can access the location you want to add 
    your entry to</li>
</ul>
<p><h2>Custom Splash</h2></p>
[[Image:customsplash.jpg]]
<ul>
  <li> Before 3.3 splash was a custom SWT application and not extensible except 
    for the image</li>
  <li> Now we have org.eclipse.ui.splashhandler</li>
  <li> You are given a Shell to fill in whatever you like</li>
  <li> Your custom splash only appears when it is bound to your product id</li>
  <li> Remember there is no workbench yet so stay in SWT code</li>
</ul>
<p><h2>ErrorHandling</h2></p>
<ul>
  <li> Constant error dialogs are annoying if it is an unexpected error that occurs 
    frequently</li>
  <li> To handle more eloquently use StatusManager in org.eclipse.ui.workbench</li>
  <li> You can implement your own status handler using the org.eclipse.ui.statushandlers 
    extension point</li>
  <li> We are going to handle errors in a non-intrusive way</li>
</ul>
<p><h2>SWT System Tray</h2></p>
