Why does my Project tab look different?
Unity allows us to customize the user interface. Everyone has their own favorite. I prefer a one–column layout Project tab instead of Unity's default two–column layout. To change this, open the context menu in the top-right corner of the Project tab, as shown in this screenshot:

When working in a team, you will notice that every team member has their own layout preference. A level designer may like to use a big Scene tab. An animator will probably use the Animation and Animator tabs. For a programmer like you, all tabs are fairly important. However, the Console tab is the one that you will use a lot while testing your code. I mostly prefer a layout pided into four columns from left to right, Scene, and Console, then Hierarchy, then Project, and finally Inspector.
It looks like what is shown in the following screenshot:

If you have trouble with moving tabs around, refer to the Customizing Your Workspace chapter in the Unity Manual.
Feel free to change the interface however you want. But try to keep the Console tab visible all the time. We will use it a lot throughout the book. You can also save your custom layouts in the Layout menu.
The Console tab shows messages, warnings, errors, or debug output from your game. You can define your own messages to be sent to the console.
