Phantom - Add "zig-zag" toggle

[Toletheus]

Minor issue - when using Phantom in combination with the "Switch Like Home" add-on, the zig-zag behind the icons on the home screen doesn't center vertically under the icons the same way as normal. Still looks fine, but I would request that a toggle be added to turn optionally off the zig-zag pattern for users who don't care for it.

Thanks for your support!
