Extendable user profile fields and UserLister macro improvement

Hello support!
I want to use UserLister macro for showing user list in table mode showing additional profile fields such as Phone, Position, Department, Location etc. Hope it's not a problem to extend this macro for use a few new parameters such as "display-mode=table" and "show-additional-fields=Phone,Position,Department,Location" (for example).
Other thing - I need to add a few fields to User Profile and currently i'm not able to do so - this new feature will be realy helpfull.
Please do so!

Thanks in advance.
