Answer

I know right, I use a chromebook and it seemed a bit unfair that I can't use my special.

Remapping keys would be nice. I find the numbers (1 and 2 for potions) aren't the easiest to reach.
Support for additional gaming mouse buttons (side buttons) would be good as well.
Sorry Rezoner, I understand this would require more work to support your scroll direction control combos.

I think by typing /kill or another command, you could respawn your character or perform other convienient things.

I am on it now. It will be released with the next update - this week for sure.

You can now customize controls in settings menu. There is also experimental support for gamepad.
