Configuring the tab widgets

(Currently Castle specific guide, not generic) 

In your hierarchy you will see a Tabs widget. This indicates that the widgets below it are parts of a tab structure.

If you open the first flexbox under and go to 'Tabs' you will see the name of the tab, this is also the name the user will see. Here you can rename the tab if you want it to be named something differently. 

By removing this flexbox and the structure below it you will remove one of your tabs in the structure.
