1) The standard shutdown (power) icon, and the restart (circular arrow) are almost universally recognised (to the extent that you wonder if we could actually remove the text).
3) if you inadvertently change your language to a language you don't actually understand, you have a hope of selecting the correct option if you can recognise the icon :-)
Rationale for adding icons:
1) The standard shutdown (power) icon, and the restart (circular arrow) are almost universally recognised (to the extent that you wonder if we could actually remove the text).
2) Colours only work if you can discriminate between then. Red and green are alas an unfortunate combination (http:// en.wikipedia. org/wiki/ Color_blindness #Red.E2. 80.93green_ color_blindness)
3) if you inadvertently change your language to a language you don't actually understand, you have a hope of selecting the correct option if you can recognise the icon :-)
