Mission Center 1.2.0 adds battery monitoring and expanded hardware metrics

The open‑source Linux system monitor Mission Center has released version 1.2.0. The update introduces a dedicated Battery page in the Performance tab, showing real‑time input and output graphs, charge level, health, capacity, voltage and a week‑long charge history.

Additional enhancements include per‑partition disk usage details, a new CPU graph that can display temperature, power draw or frequency, memory page compression statistics (zRAM/zswap), and flexible GPU graph options for encode/decode activity, power draw, clock speeds or temperature. UI improvements add smoother graph rendering, pause‑on‑Ctrl, new keyboard shortcuts, and the ability to gray out zero values. The Snap package now uses the core24 runtime and the AppImage has been rebuilt with quick‑sharun, reducing size and removing the FUSE dependency. Numerous bug fixes address CPU temperature reading on the Steam Deck, HiDPI icon rendering, SMART dialog width, and phantom CPU usage spikes.
