Hi there,
I've been using Input Director for years now, as a gamer, and it works *very* well for when I'm multi-boxing in MMOs like World of Warcraft, SWTOR, LOTRO, and so on, and I've been very happy with this software in that use case.
However, I also play games like Star Citizen and Elite Dangerous, which I also sometimes multi-box, but unfortunately there's no support in Input Director for the different input devices I have plugged into one machine working on the slave machine in those games, which greatly limits the utility of the software in this use case.
I imagine this is a very niche use case, but I'd find it very useful to be able to have game controller inputs from the master being communicated to the slave device(s) also be supported.
For reference, on my master PC I have the following gaming controllers connected
1x Flydigi Vader 4 Pro controller.
