v0.8.20

New in 0.8.20

• Processes: sort by anything. Click a column title, or use the new Sort menu: name (A to Z), CPU, the 15 min / 1 hour / 6 hour average, memory or GPU.
• GPU column. Every process shows its share of the graphics chip.
• Calmer rows. The buttons on each row are now one ⋯ Actions menu (What is this?, Explain, Optimise, Kill, Force kill, sudo kill, More). The columns are wider and full process names fit. Badges are small icons; point at one to read it.
• "now" is now "CPU".
• GPU on Overview. A GPU chip sits next to the thermal chip on the main gauge.
• Clickable status chip. Click "memory pressure" (or disk, battery) at the top to open the tab about it.
