What is Edit Blind mode?
Edit Blind allows you to adjust scene values without affecting the current output. This is useful for when you want to make changes but don't want the lights to update while making them.
To enable Edit Blind mode, tap and hold any editable scene's name label, when it isn't already active, and select "Edit Blind". Alternatively, you can tap the scene's name label and in the view that appears, tap the "..." and select Edit Blind.
