Filter Users By Subscriber allows you to select your users in User Manager > Filter Users by whether or not they have subscribed to your newsletters. You can then assign selected users into specific user groups (1,2,3 refer to the groups shown on a user record) which you may want to do for segmentation and emailing purposes. NB Email Manager will not send to users who are not marked as subscribed.
Filter Users who are ungrouped allows you to find users who have been entered without being assigned into a group, so you can quickly identify them and then add them into the desired group.
Script Finder is a new program which allows you to scan areas of the website to find scripts that have been embedded in the site, such as 3rd party apps or tracking which may introduce cookies and therefore you need to be able to turn off those scripts in conjunction with Cookie Manager.
