Are you saying you want to add some gain to your entire timeline after you've gone through and colored everything, or you want to add gain to a single shot, after you've already added (for example) 4 different nodes to accomplish your look?
[Geoff Johnston]"Is there a "Master Gain" control for adjusting the Output Gain of the Master "Node(?)"? In other words, can I animate the gain on all nodes at the same time?"
You could if you add a 5th serial node at the end of the tree just for keyframing gain. Or do it as a Timeline grade.
Oh wait, I just realized that putting a keyframe in the "Master" also creates keyframes for all the other nodes in the exact same spot. So this is a huge discovery for me, and answers the first part of my question.
However, the second part of my question still stands. Can I adjust the Output gain for all my nodes at the same time without having to do each one separately?
I'm currently doing a project with a huge amount of nodes, and it's a traumatizing experience having to change the output gain on every single node separately. It seems like I shouldn't need to do this, given how advanced this program is.

If I understand your question, the answer is no -- you have to adjust the output gain on every single node separately. Me personally, I just look at the end result and then make an adjustment if necessary. Not every node is a key; not every node needs a key gain adjustment. There's also Primaries, Secondaries, Log adjustments, Contrast, Curves... there's a lot going on here. It's a huge subject.
Just as with slowing down a car, there's probably 5 or 6 ways to do it, but generally using the brake works well for me.
I think we are all a bit unsure why you feel you should adjust the key output gain on every node in your project...unless you are doing a ton of compositing, which still don't think is Resolves strong point.
Perhaps a couple of before/afters, with a shot of your nodes might get someone thinking of an easier solution, or a better understanding of your problem.
I think, generally, we are all along the lines of Karsten...just do one final adjustment node, if its consistant across the board, you could save it as a still, and do an append node to all your other nodes, or as a timeline node as just mentioned.
