From 539e2eced0f35144d7841477e5cdc2d8c521e82a Mon Sep 17 00:00:00 2001 From: Patrick Scott Date: Thu, 13 Jan 2011 11:27:38 -0500 Subject: Different approach to auto signin. On startup, attempt to log the user into google sites. Show a progress dialog that the user can cancel if login takes too long. Add a new preference for toggling auto signin. This preference shows the current account and allows the user to choose the account to use. If there are no accounts, the option is disabled. The saved account is validated each time it is accessed in case the account was removed.
