• Per-value warning thresholds with color changes
• Fully customizable colors (normal + warning, separate for temperature)
• Custom font family, size, and bold toggle
• Fahrenheit support
• Three update speed presets (Low / Medium / Fast)
• GPU model name display (fetched via lspci)

Colors — normal/warning colors for usage; optional independent color set for temperature

Font — search any installed system font, set size (7–24pt) and bold; live preview

Performance — Low (5s) / Medium (2s) / Fast (500ms) update intervals
