Here's my current VIAL keymap. For now, it's just the default game mappings, plus one or two extra and the Enter key, because I've found it occasionally useful. The toggles are just more buttons, though except for a couple of fun ones (cloak and arming missles) I left those to more administrative keybinds.

I did up the firmware properly, (although cramming VIAL into an old-school Pro-Micro is interesting) so I could change it around if I need to. There's still room for one more layer, but I haven't implemented it yet. I am using "POS" keycaps instead of proper stabs, so I was able to tweak the left thumb in to a mini-cluster. I could eventually do the same for the main Fire button, although the orange Afterburner is wired as a single key (kept me at 40 exactly and made my matrix math tidy).
