The Interface Customizer Dialog allows you to visually customize the Serna GUI layout for the current document, for the current template, and for the default views of Serna. To learn more about the views, see Serna View Customization.
Figure 1. Interface Customizer Dialog

The Interface Items tree shows the structure of the current GUI layout.
The user can remove, move, and copy the parts of the layout by removing, moving, and copying the items in the structure (use ,
,
and
buttons).
The Available Items palette contains the Serna GUI components that may be inserted in the structure, and become visible. Every component may be a child only of a specific list of parents (e.g. menu separator cannot be a child of ContentMap), see "Serna GUI Item Reference Guide".
To insert new items from the component palette, use / and buttons.
Every GUI item has an identifying name and some other properties displayed in the Item Properties pane.
Some GUI items have the action property. The value of the action property is the ID of a Serna command. One may change a GUI item action to change the behaviour of the item when it is activated (e.g. button is clicked, menu item is chosen).
The properties of an action are displayed in the Action Properties pane. Here are the most common of them:
The ID of the action (corresponds to the value of the action property in the Item Properties pane).
The inscription on the action control.
The icon for the action control.
The tooltip for the action control.
The hot key for the action.
The ID of the called command event.
The "enabled/disabled" state of the action control.
The ability of the action control to switch between alternate ("on/off") states.
The "on/off" state of the action control.

By default, every change made to the Serna GUI is not saved automatically: you should save it before you close the document. If you forgot to save changes then open the document from the recent file list: the GUI with your changes will be restored. For instructions on how to save the view, see How to Save View.
