The new version of this free open-source Rust written and GTK4\/LibAdwaita based application finally added monitoring support for laptop battery<\/b>.<\/p>\n

It now displays a battery page in the Performance tab, drawing the graphs for battery input and output in real-time, as well as the battery charge info over the past week.<\/p>\n
And, it displays current battery percentage, health, energy in Wh, charge circle, and other information such as capacity, voltage, and charge threshold.<\/p>\n
The disk storage monitoring page has been updated with per-partition usage details<\/b> information, allowing to take quick a glance at how much disk space is used for all the volumes.<\/p>\n And, the CPU page now includes a new temperature graph<\/b> in bottom, which can be changed to power draw graph or CPU frequency graph via right-click menu.<\/p>\n At the first run, the app will show a dialog asking for additional setup for CPU power draw, per-process network usage, and lm-sensors setup. User can re-launch the dialog at any time from the hamburger menu and revert the setup.<\/p>\n Other UI changes in the release include ability to change what to draw in the middle graph in GPU page, display zram<\/b> or zswap<\/b> memory compression statistics in the Memory page, per-process swap usage<\/b> instead of shared memory in Apps tab, and option (in Preferences) to gray out zero values in the Apps page.<\/p>\n Mission Center 1.2.0 also improved the graph drawing backend for smoother rendering and animations, and less stuttering on application startup. <\/p>\n It as well updated Snap package<\/b> to use core24, and updated AppImage to use quick-sharun<\/b> instead of FUSE file system.<\/p>\n Other changes include:<\/p>\n There are as well various bug-fixes and other changes.
