Unfortunately I cannot give you any real news on this. We are interested in a solution for our own games as well, so we are indeed working on it. But it seems to be more tricky then we have anticipated. There is a nice system to control the mouse cursor via the gamepad, but it is C++ based, so not an option for the MMS. The other alternative is to “jump” between menu elements like buttons, checkboxes etc. via the gamepad buttons. But that would require a logic in which order to jump, incl. left/right with multiple columns, highlighting those elements, etc. As of now we have not found a solution that is a) robust enough to be shipped to the public, and b) implementable in a reasonable amount of time. We neither want to ship a workaround that would only work for some MMS users, nor do we want to develop a solution for weeks or months, which would cost to much time and money …
But we still do have that on our todo list for sure!
Nope, not as of now, you would need to implement such a menu on your own.
Cheers!
