Feedback on GSoC Proposal Submission: GRC Sub-flowgraphs and Minimap Navigation

Dear GNU Radio Community,

I hope you are doing well.

My name is Suryasaradhi, and I am currently pursuing an MSc in Electronics Design and Technology at the University of Siegen. I am writing to share my GSoC 2026 proposal titled:

"Enhancing GRC: Built-in Sub-flowgraphs and Minimap Navigation"

This proposal focuses on improving the usability and scalability of GNU Radio Companion (GRC), especially for large and complex flowgraphs. The key contributions include:

- A built-in sub-flowgraph system to enable modular design without requiring external Python bindings or recompilation

- A minimap navigation system for intuitive visualization and navigation of large flowgraphs

- Improvements to workflow efficiency, design scalability, and overall user experience

I have already developed working prototypes for both the sub-flowgraph system and the minimap (GTK), and I am currently extending support to Qt. The proposal also includes detailed system design, implementation strategy, and a structured timeline.

I would greatly appreciate your feedback and suggestions to further refine the proposal. I am particularly interested in aligning the design with the current GRC architecture and community expectations.

Please find the detailed proposal attached as a PDF.

Thank you for your time and consideration.

Best regards,

Suryasaradhi
