Add Plugins to his own server

Is they any plans to add plugin funktions to servers ?
For example: A Voice/Sound Plugin where you can change the sounds from Discord or that people can programm there own pluggins and add them to there server´s.
It would be nice and the users could then bring more creativity into their servers!
It's just an idea but it would be a cool feature and I think that many people would be happy about it.
