Screenshot of Shutdown Dialog
In the shutdown dialog in the "Turn off Computer" text along with icon appears as one button, however it is not.
If you click on the text "Turn off Computer", your computer immediately shuts down. However, if you click on the icon, you are presented with a drop down menu with more options (suspend to disk/ram). Needless to say that this is unexpected and irritating (notice also the drop-down arrow, being on the left of the icon instead of the right side).
A fast fix would be to merge these two buttons into one button and also move the drop-down arrow to the right.
But this is also little against HIG rules, since you take directly action from a drop-down menu (normally you *choose* something from a dd-menu and confirm this with an OK button or similar). So IMHO in the long-run a rethink/redesign would be due.
The Plasma 5 version of the UI doesn't do that anymore.
