# Utility Elements

## Address Controller

The Address Controller element allows us to check whether we have certain addresses labelled within SankoTools and to create new address labels.

We paste in an address of interest, check whether it has a preexisting label and then create a private label:

## Notepad

The Notepad element is simply a resizable notepad we can add to a layout for extra functionality or to explain how to use certain elements should we wish to share the layout:
