Code review comment for lp:~cosmos-door/ubuntu-keyboard/japanese-keyboard-rebooted

Looking really good, just a few small things needing fixing:

1) The cursor keys move two characters at a time (it looks like they're moving the cursor on both the press and release events)

2) In the character selection pop-over the characters that aren't currently selected should use the same colour as the selection pop-over on the other keyboard layouts (this is done by setting the opacity to 0.6 when not selected)

3) If touch feedback is enabled in settings then sliding between characters on the selection pop-over should trigger haptic feedback via pressEffect.start() (same as on other keyboard layouts)

4) The copyright year on a lot of the added files is listed as 2012/2013/2014, this should be 2015 since these are new files

5) Is it correct that the URL and email layouts should be a non-Japanese qwerty layout? (If so it might be worth populating the URL key with useful Japanese TLDs like .jp, .co.jp, etc.)

6) Could you add a comment to the modifier.js explaining the purpose of the map and normalize arrays?
