I stumbled upong this: https://github.com/Tomas-M/iotop

But, the UI is not very intuitive (doesn't follow Vim bindings), and I think it could overall benefit from a nicer UI like the one used in https://github.com/EdJoPaTo/mqttui

I'm a little lost on where to start, so I'm wondering if there is someone who'd like to collaborate with me on this and we can learn along the way?
