These are my recommendations/thoughts
- Make the gears glow yellow when you hover over a section with your mouse.
- Gears should also be slightly lighter so they stand out better. They're too dark right now.
- Fundamentally, I believe the gear icons should be a shortcut to the advanced functionality without having to expand a section. There should be a button under each section for "Advanced." This is much more in line with standard UX. The gears are too much of a departure from user understanding for you to force people to access functionality through them exclusively.
