- last login name is saved
- wait image should be displayed right now - the qApp object is destroyed before the launcher is started -- this should prevent some semaphore permission problems - added a (very basic) crash handler - added a simple "respawned too fast" detection in case of qt/e fb problems - if opie-login is started with -a <user> or --autologin <user> it doesn't prompt for a username/password - instead it loads qpe directly using the specified user account So even if you are not running multiuser, you should now start qpe with: opie-login --autologin=root
