Feature Request/Idea:
Users receive a message when they try to run a command that is on cooldown (similar to the "not enough points" or "not the necessary rights" message)
Details:
Add an additional field to the command editor that allows to specify a message that is sent when a command is on cooldown.
Usecase:
Currently users receive no feedback when they run a command that's on cooldown, so they don't know if it doesn't work or if something else went wrong.
