Can we please get rid of :// for denoting protocols?
Like it's fine to still support it, but how come : doesn't suffice? I hate having three forward slashes when I'm accessing a remote or virtual filesystem.
I love you GNOME but admin:/// is a travesty. 
EDIT: Actually, what about > ?
https>cubhub.social and admin>/home/rusty
mostly because I like Matrix's @user:server.tld and matrix:@user:server.tld would like dumb but matrix>@user:server.tld would be pretty clutch
