When a shader being complex, the number of nodes may increase and make the graph not easy to read. 2D Effects Creator provide a simple and useful node to manage the nodes - comments node. You can group several nodes in the comments node and add comments on it.
You can add a new comments node from node menu Utilities>Comments Node. Resize the comments node by drag on the bottom-right corner.
By drag and drop the nodes inside the comments node, you can group several nodes together and move all nodes.
