In user account configuration, what is the Edit button good for?
As a side note, it appears not to be possible to edit your full name after
you've added a user account without first deleting the account entirely. Is
that what the edit button is supposed to help with?
The purpose of the Edit button is documented in the help text beside the screen,
however, at this time the edit button does nothing (a bug) so that probably
would lead to confusion :-)
Fixed in the latest beta of the installer.
