Active Within X Days Module Dolphin with Admin

Hi, I'm wanting a feature that enters below each user when they were last active.. ie. Active within "Today" Active within 1-2 days, Active within 1 week, 1 month, 2 months and over 3 months etc.

Also I require an admin page that can filter say all the members that have not been using the system for over 3 months, and to delete them from the system, or change their status to Inactive and automatically send them an email saying they need to return to re-activate their account.

Please let me know if possible.

Thanks
All the best
Anthony
