I may be wrong but, I believe tickets tags are kind of "left behind" on freshdesk.
Tags can be very, very helpful for longs workflows ticket report analysis.
For example, for any step from a workflow we add a tag (i.e. Customer Return, Warranty, Refund, etc).
When we can have a "tag use" AB report (comparing similar last period), we can check what steps of the workflow have increased or decreased.
