Really great and thank you!! You seem like the man to ask, how would you go about doing some of the expressions you would in AE but with Fusion? Say wiggle (to animate opacity) or linking one node to another? So when you change the color of one node, it updates the same kind of node somewhere else in the chain? Also how to do a hold keyframe (if you want to extend the timeline before / after)? Keep up the amazing tutorials!
You can right click the node and in the context menu you'll see a "show" menu. In Fusion's settings you can set it to show at all times but that gets annoying so I manually show the nodes I need.
