jsCpuMonitor

Floating always-on-top window showing real-time CPU utilisation for
every logical core. Displays usage history charts, per-core frequency,
CPU temperature and power consumption (Intel RAPL).

═══ HARDWARE ACCESS (optional) ═══

For temperature, power and frequency readings:

 sudo snap connect jscpumonitor:hardware-observe               

Without this the app still works — those fields are simply hidden.
No reboot or restart required.

Features:
- Per-core area chart with 60-second history
- Total CPU aggregate chart
- Per-core frequency (via cpufreq)
- CPU temperature (x86pkgtemp / coretemp / k10temp)
- Intel RAPL package power in watts
- Window position and size are remembered across sessions
- Crash reporter with optional e-mail support

Supported systems:
- Ubuntu 24.04+, Fedora 40+, Arch Linux, openSUSE Tumbleweed
- Any Linux desktop with X11 or Wayland
- x86_64 (64-bit)
