Mactivity 1.2.0

• Menu bar readout is drawn rather than typeset: each metric gets its own glyph,
  colour and live sparkline. Choose values, graphs or both.
• Right-click the menu bar icon for Show, Cleaning Mode, Settings, Check for
  Updates and Quit, instead of reaching them through the panel.
• Threshold alerts, off by default: sustained CPU load, critical memory
  pressure, low disk space and low battery. Each waits for the reading to hold,
  then stays quiet for fifteen minutes.
• Top processes can be ranked by memory as well as CPU, and the card links out
  to Activity Monitor.
• Battery shows time remaining, maximum capacity, cycle count and condition.
• Ring gauges replaced with stacked horizontal meters. Four circles in a panel
  built entirely from rectangles read as decoration, and the percentage had to
  sit inside the ring, which left the subtitle crammed underneath at 8pt. Label,
  detail and value now share one reading line.
• One rule for load colour across the meters and the per-core bars: the accent
  colour up to 70%, yellow to 90%, red above. Colour now means load rather than
  which metric, so the panel only lights up when something is wrong. Cores
  previously turned yellow at 50% while nothing else changed colour at all.
• Per-core bars sit in tracks and are centred, instead of being a row of stubs
  across a third of the card.
• Settings split into Panel, Menu Bar, Alerts and General tabs. It was seven
  cards in one scroll; each tab now fits without scrolling, and the popover no
  longer changes height by several hundred points as sections open and close.
• Settings controls line up in a column. A bare Toggle("CPU", isOn:) sizes
  itself to its own label, so every switch sat at a different x — most of what
  made the pane look unkempt. Section headers moved above their cards so the
  group names can be skimmed down the left edge.
• One card surface, one type scale and one button style across the panel,
  replacing the eight hand-rolled copies that had drifted apart. Rows highlight
  on hover, and the settings pane crossfades instead of snapping.
• Idle transfer rates read "0 KB/s" rather than "Zero bytes/s".
