Well, that just went that focus part.
Add-ons for different keyboards and layouts are always necessary, but maybe I give up my previous plan to offer lots of color combinations.
The Moogle kit keys came out quite well, except that they not accurately match the Cherry colors. But if we go for a different color, that will not be too much of a problem. If SP hasn't got the arrows or ther symbols we need, some few SVG graphpics for that purpose won't kill us.
