Why Colorists NEED a Stream Deck to Supercharge Their Color Grading in Davinci Resolve 

It's quite sophisticated, worth watching the preset creator video. I've created something similar myself, but I've come to the conclusion that you should only have one screen on the stream deck for each tab and the functions you use the most, and switching between screens often takes longer than using the mouse. Definitely the Stream deck is a blessing and everyone should take the time to create their own macros as everyone has different preferences. You can also just buy icons from the creator of those presets.

Sorry to say, I have a stream deck myself too, but for adding node trees you are much faster when you add them in the Powergrade bins, this also gives you an opportunity to see what the result will be. Other then that the stream deck is very helpfull for me of course.
