Dear Maintainer,
  May I suggest to rename lightdm-settings (tool & package) to something like
"lightdm-slick-greeter-settings"

Indeed, as it can be confirmed by the code itself, this GUI aims to guide user
to configure "/etc/lightdm/slick-greeter.conf".
With its current name, it may lead users to believe that they can configure
lightdm as a whole.
This may be the case in the future, but it is not its current functionality.

So, to avoid this confusion and to be consistent with other similar tools (eg.
lightdm-gtk-greeter-settings), I propose renaming it to lightdm-slick-greeter-
settings

Best regards
