Once the application has been created, we can start to build up the application with application files. These are the files that, when put together, make up the application. When the application is created, an application scope is also created for the application. On the creation of the application, you will also be put into the new application scope, so it is important to be aware of this.

You will also see that your update set has changed once you create a new update set to a new default update set for the application scope you are now in. As you are in the application scope of your new application, any customizations made will be added to your new application.

To keep track of the current scope and update set, it can be useful to show the application and update set picker when developing. These two options can be set in the Developer tab of the system settings, which can be seen in the following figure:

By setting the two picker options in Figure 12.4, we are then shown the current application scope and update set at the top of the screen in the header bar. These are shown in a drop-down field, so both can easily be changed if required.

We can see here both of the picker drop-down fields that are displayed in the header bar:

These picker fields are especially helpful if you are working between update sets or in multiple scopes for your current development.

Now that we have created and started to build our application, we can move on to the development of our application.
