I was thinking about this the other day, when we were talking about when it is or isn't useful to see player numbers. Lots of commands have only a handful of possible arguments--e.g. "on" or "off" or player numbers--and I could imagine the game showing you a list of possible next choices, like a dropdown menu but upwards... a dropup menu...



Sorry for the ugly tileset in this mockup

For commands like /kick and /mute, you wouldn't need to worry about player numbers at all, you'd just pick the player's name from the list. But a couple potential issues:

• When you're chatting something, it's drawn below anything that anyone else has chatted recently, so this dropup menu would have to overlap that... maybe that's okay
• How would this be controlled? The Up/Down keys, while chatting, are otherwise used for when you want to repeat something that you chatted in the past. It feels confusing to overload those keys just when you're in this command typing context, like somebody would inevitably make a mistake at some point.
