Lack of interest Extended admin user list

I would love to have a more usable userlist in the admin panel
PReferably the listed and filterable usergroups
So I can immediately see who is in what group
Thanks.. that help a bit.
But I would love to see in the general userlist their groups , and it would even be more amazing when I could click on the groupname to filter directly only people in that group.
Maybe someone is interesting in building such an addon, otherwise I might do that along the track somewhere
