Hi, is this issue still open? I'd like to contribute

[vaithak]

Hi @cchiu727, yes this issue is open. It would be great if we can first discuss some potential approaches and then go ahead with implementing it.

[cchiu727]

Yes, I'd be glad to. I will take a closer look at the code and reply with some ideas very soon. 👍
