Here is minor update with some new features added and few minor fixes. Plugin now adds few more options to control the users panel with additional column for last users login date. For this plugin uses another built in feature that tracks date when users login.
You can set to display date only or relative number of days/weeks/months since last login or both. If user has never logged in, you will see date of registration. This will be used in following releases to allow you to delete user accounts based on last login date.
