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

Hi,

I have updated the proposal by Adding another feature called as Runtime Perfomance Overlay. This feature would colormap the GRC blocks based on the blocks execution delay. It acts like a heatmap in the node graph this becomes useful to people who needs to identify where exactly they are having bottlenecks in their flowgraph design and update it accordingly.

Regards,

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
