As I've had the luck to collect over 25 wingmen/autons in 1.02, I've noticed that the 'C' Comm screen doesn't go beyond 'Y'.
So if you have more than A to Y wingmen you can't order them around directly.
Since 'Z' seems free, could it be mapped to 'Next Page' or something similar so you can have a swarm of your own? I've heard the Comm screen is hardcoded so this goes beyond modding.
On another note, it'd also be useful if cargo-capable wingmen (Mule Autons and any modded ones) could show free capacity like a 3-digit number in tonnes, displayed before the hotkey like: "075 [A] 330Mule Auton".
It would be more elegant than messing with the UGWingmen source to try auto-renaming mules after each docking like: "[A] 330Mule01 075".
Some method for the user to sort the wingmen in the list (beside gating out of the system while leaving some of them waiting) would also be nice.
