It's nice that a full description of what the different power buttons
do are in the mouseover tooltip
But can we get the label on the tooltip as well as the description?
- shutdown", "log off", "switch user",

the descritions are nice, but the label should be there as well.

example:
"Switch Users: Let's another user log on while your programs and files
remain open."

instead of
"Let's another user log on while your programs and files remain open."

I know what the labels are, but not nec the icons. they aren't all
exactly different colors either. Of course anyone can learn and
memorize over time, but the idea here is to facilitate user-
friendliness as much as possible, so i think there is room for this.
