In order for you to see a view in the left panel, it must be in one of your view groups. Each view must be assigned to at least one view group, but it can also be assigned to multiple groups.
Views can be assigned to groups in various ways depending on your level of access in the application:
All users can do so from the Save View As window.
Users with the ability to create new views from scratch can right-click a view group in the left panel and choose New View. The view will be assigned to that group.
Users with access to view explorer can choose the view group(s) in the Properties window for the view.
Administrators can do so from the View Group window.
Users with a casual or advanced level of access can save shared and personal views into view groups that are part of their user profile group. Users with a view or security administrator level of access can save global, shared, and personal views into any view group that exists in Stratum.Viewer.
