Hi there,
I've checked the other issues, locally built the binary to play around with it but given the recency of the project, I'm not sure if you plan to eventually implement per process level stats/battery drain over time with nice graphs/charts? Current it is only system-view level. I bet this isn't easy, it is also the thing I miss the most now in Linux compared to other operating systems like Android(amazing), iOS etc.
I'm sure this is no easy feat. Also, thank you for your courage and hard work to take on building & maintaining this project!
