 The weather card beside it is not part of the tabs and stays visible.
 
+The two timeouts on the General tab are the `idle.screensaver` and `idle.lock`
+values in `~/.config/blob/shell.json`, in seconds. The minus and plus buttons
+step through 1, 2, 5, 10, 15, 30 and 60 minutes (and 2 hours for the lock),
+starting from whatever the file holds, and the idle service picks the new value
+up straight away. A value set by hand that is not a preset is shown as it is.
+While Stay Awake is on, the tab says so, since neither timeout runs then.
