ICE offers the user another interaction method as an alternative to the application UI. This is called the Immersive UI because it works directly on the Igloo canvas.
Enabling the Immersive UI
There is a toggle switch in the top right corner of the ICE application UI called Immersive Mode. Click this to enable or disable the immersive UI.
The Immersive Toolbar
Once the immersive UI is enabled, the immersive toolbar is displayed on the canvas. By default it will appear in the top left corner and it can be moved by left click-drag on the left edge of the toolbar.
