Announcing: Enhanced employee list page

As part of our efforts to streamline the dashboard for growing retailers (both in headcounts and storecounts), our team released a series of improvements to the employee list page!

- Can filter employees by location
- Can filter employees by security role
- Can see which locations and security roles each employee is assigned to without having to click into each profile
- Users with the "Can manage employees" permission can only edit employees under their locations
- Administrators are colored green to highlight their elevated access level
