vishal2376/mindmap ? reverse-engineered prompt

Build me an Android Studio and IntelliJ plugin called Mindmap that helps me understand Kotlin code by showing an interactive call graph for whatever function my cursor is on. When I press Alt or Option + G, it should open a visual view of that function, with callers on the left and called functions on the right, and let me expand deeper in both directions.

I want it to feel like a real tool for exploring code, not just a static diagram. Include a tree view, a mini map for navigation, search, hover cards with useful details like the function signature and file location, and easy ways to click a node and jump to that source. It should also support hiding and restoring nodes, tracing through abstract or interface functions to the concrete implementations, and a simple way to merge or re center the graph while I explore.

Make it look polished and usable inside the IDE, and if you need current plugin API details, look up the latest docs online.
