Hi,
Something like this would be very useful. A lot of times when I'm making commands for the people I moderate for, I have to make them mid-stream. Not being able to add in cooldowns for commands as a moderator can be very frustrating; the streamer doesn't always get a chance to add it in through the client which can, on occasion, lead to commands being overly used. I know you'll probably say to just add in access levels, which I do do where appropriate, but on the occasions where it's been something that everyone should be able to use, not having a cooldown has been quite a nuisance.
There's also been times where an existing command's cooldown has had to be altered, either increased or decreased, for stuff like stream events, overuse etc. and none of the moderators have been able to do anything about it.
I don't know if/how hard this would be to implement, but it'd be a very hand feature to have.
