Hello Lionel77,
actually the default Users list follows the same logic and layout as the Articles. It makes use of the "Blog" template, and the Item view layout is "Seb One". By default there is only the username displayed. You have to go to your list&search type Users -> Item (Views) -> Fields (Options) ... and add all extra Profile fields. Assign them to Mainbody position or any other position below.
(If you don't see the extra profile info fields... you have to change the Selectbox / App Folder from User to the correct sub-folder Profile!)

@Seblod ?! Somewhat strange, IMHO... because I am viewing a parent/child folder hierarchy, I would expect to see any subfolder content automatically. i.e. If I am in AppFolder "User", it should also display fields from "Base, Basic, Profile".
