I used to open Task Manager multiple times just to check RAM usage, CPU/GPU usage, temperatures and other system stats. I wanted something that could show all of this at a glance.
It's Similar to the popular macOS app called Stats
It supports CPU, RAM, GPU, disk speeds, network usage, CPU/GPU temperatures and customizable layouts.
It's completely free and open source, with no paywalls or monetization :)
