[LightDM] several qustions about 1.4

[Frantisek Hanzlik]

All LightDM gurus,

first, many thanks for this SW piece.  I'm just trying v1.4.0
(with lightdm-gtk-1.3.1), and when I can ask for some details which
i'm not able configure:

- how display (at login screen) all available users? In login window\
  I see only one line with last logged-in user

- how I can display users which accounts are in LDAP directory (not
 only these from /etc/passwd)

- when I see in login rows, at login window, user full names (GECOS
 in /etc/passwd), is there any way (e.g. when move mouse cursor over
this users line) how uncover users login name? (sometimes login
names are totally different from GECOS names, and for administration
(not only) purposes would be this very nice)

- at upper LightDM greeter graphical panel, in right corner, I see
  two icons: one for impaired peoples which at right click offers
"large fonts" or "high contrast", and quite on right icon which
look as switch and IMO should offer things as shutdown / reboot /
hibernate etc. But this icon does nothing - left click is without
response, right click does nothing too.
Also, should be there any keyboard shortcuts for this poweroff etc
 action?

- at login screen I see users which names are listed in
"/etc/lightdm/users.conf" in "hidden-users=" list. It is sort of
 some my mistake?

- when is possible display individual users at login screen, is
 possible display its thumbnails?

TIA for all recommendations.
