Reply to S4 MK2 mappings

Not to ruffle any feathers here, but.......It seems that the MK2 was released, not well received, and we've all kinda moved on. It's like the MK2 is the windows vista of the controllers market . That being said I'm I the s2 MK1 and aching to move up to a 4chan controller. I humbly ask, are there any custom mappings out there for the s4 mk2, and if not is anyone working on anything? Thanks in advance.
