The basic fundamentals of managing the My Loops page under an Admin profile are the same as those used for any Agent profile. Check out the following agent articles if you're new to dotloop or need a refresher.
There are a few key added features to note under Admin profiles when it comes to Filters and Sorting:
As an admin, you have the additional option in your filter settings to filter by loop tags that you have created. You can find this option at the bottom of the Filters Panel.
Sort by Agent Name
You also have the additional option to sort by Agent name, which appears at the bottom of the sort dropdown list.
