Comment 9 for bug 458376

The general pattern is that when an item in a status menu opens a window, that window shows a superset of the information from the menu. The battery status menu shows the charge for a battery, and a menu item opens a window that shows the charge *and* other things. The sound menu shows the volume, and one of its items opens a window that shows the volume *and* other settings. The keyboard menu should show the current layout, and one of its items opens a window that should show the current *and* other settings. In each case, we should cater for people who want to access the information or settings without having the relevant menu in their panel at all.

A simple solution to this is to add a column of radio buttons to the left of the "Layouts" list. Make sure the radio buttons do not interfere with drag and drop for items in the list. And make sure to update the radio buttons whenever I change the layout using the keyboard combo.
