In my other life I am a graphic designer. I was thinking about how the design programs like "photoshop, illustrator and indesign" organise designs in layers and wondered it that would be something that could work with charting.

1: Layers
For example, I could have EUR/USD on the main layer, then on layer 2 I may have a price overlay, on layer 3 I may have indicators. On layer 4 I may have all the guides and indicators I need for a scalping strategy, on layer 5 I may have everything i need for a different strategy.

Allow the user to organise, view, hide the layers.
