I added full black keys.
I must admit I'm a little lost sometimes, I know my layout by heart, but I guess I need a visual "starting point" to position my hands very quickly and start typing.... Well I guess I'll be used to it in a week or so.
Also, I'm hesitating about buying all the letter in engraved white, I don't know it'll look good or not, so I'm trying to mess with pictures of my keyboard in photoshop, but it doesn't look very realistic.
