Mindmap approach to coding?

I love your implementation. I had this vision and your implementation is the closest to it.
Just an idea...
What if you can visualize your code as a mind map? Not just markdown.
Mind maps let you group ideas and move them around. I see code as group ideas (classes) that you can move around.
All the details will still be in the text view for implementation of a function. But common blocks can be identified in the code. There will be always a function name, there is a begin-end markers, there are classes with begin-end, and so on.
