Smode
Smode's interface is similar to Blenders in a few ways. Every panel's display can be selected in the top left corner dropdown menu.
Compositing
Smode composites whatever is present in the Element Tree from top (back) to bottom (front).
Smode's timeline is used whenever you need to animate an item's property.
Compositions can be nested inside the Element Tree of a composition.
When selecting an element, the Parameter panel has several tabs, notably the Generator tab with parameters on how the element is built and the Renderer tab with parameters on how the element is displayed.
The Viewport panel can toggle between the 2D view and the 3D view
