Comment 5 for bug 1383887

 I can certainly do most of the implementation without further design input if we're just going for a grid of suggestions overlaying the keyboard (much as android does); although I'd guess you might want to have some design input on how exactly that should be presented? e.g. perhaps we should have bigger fonts than on the word-ribbon to make them easier to press, closer to the key font size? Do we want any visual separators between characters? etc.
