Lock Delay version 1.1 was just uploaded to the Android Market. In this version, a user suggestion was incorporated. Now when the lock pattern is enabled, the regular slide to unlock screen will not be displayed. There were circumstances in previous versions where the user would be required to input the standard slide unlock and then the pattern too. Now, the user should only be required to perform one unlock gesture.
On a side note, I got my official Motorola Droid 2.1 update installed today and am pleased to report that Lock Delay still works as well as it did before.
