Extra configuration options Userlister macro

On the Userlister macro; Can, similar to the "content-by-label"macro an option be added to choose whether you want to show the e-mail and username of a user? Should look like this;

{userlister:groups=name|e-mail=false|username=false}

Also I would like to be able to edit the name of the group

{userlister:groups=BLABLAEXAMPLE|title=EXAMPLE}

The reason is that the userlister macro is useful, but sometimes showing too much information which is distracting.
