Queue feature for channels that have max slots

There are a lot of discords where there are channels that are capped. Having a feature where you can just sit in queue to join a channel until someone leaves would be nice. I would also suggest having like a time to accept to join. When someone leaves while you are 1 in queue you have 1 minute to accept to prevent afk people from getting in. This is just a simple suggestion instead of having to stare down a channel for a long time.
