Re-enable "component tree" in Android Studio

After updating to the last version (1.4 Beta 2) in Android Studio, the "component view" in the layout editor disappeared. How can I enable this tool again?

What is the purpose of component tree in Android Studio?

Component Tree: Shows the hierarchy of components in your layout. Toolbar: Click these buttons to configure your layout appearance in the editor and change layout attributes. Design editor: Edit your layout in Design view, Blueprint view, or both.

Where is the palette in Android Studio?

If you double click on your . xml file tab at the top it will maximize the designer window. Then on the left you can drag the window to shrink and it will reveal the palette.

I lost mine too, and then realized that they just moved it to the left side of the screen in the latest Android Studio 2.2 Beta 2. It took me a good 10 mins to find it. enter image description here
