Smooth member list movement

When there's a long member-list in a server, there are often people going online and offline. Whenever that happens, a large portion of members either move downwards or upwards suddenly. This movement happens quite jerkily and it can be a bit hard to follow. It would be nice if instead of it jerking, it would move up or down a bit more slowly so it would be easy to follow.

Here is an Imgur link to a video showcasing the problem: Click me.
