Highlight on scrollbar where you are in member list.

For servers that are community-based or have large numbers, I would like to suggest the ability to show where within the list the viewer is at in the member list. What I mean by this is to highlight where the viewer is located within the scrollbar's scrolling region so he/she can quickly scroll to that point when needing to self-modify their name for said server channel or needing to self-check what roles he/she currently has on the server, maybe even view their own profile to see what other's are seeing. 

As it stands, there is no easy way to really do this, let alone when a server has 1,000+ members.
