This page lets you configure the toolbars. You see the list of available commands (that can be filtered by specifying Category) and the list of toolbars.
To create a toolbar, press the New… button. Enter the toolbar's name. The created toolbar is empty. Add new commands to it.
To delete a toolbar, select it in the list and click the Delete button.
Hide a toolbar by unchecking the box next to its name in the Toolbars list. Change the size of the toolbar icons with the Button Size control. The Device Monitoring Studio's unique vector icon technology renders command icons at any size without artifacts.
