As a general rule, whenever an activity log is added to a ticket, if there was no user provided description, the action_desc field has the same content as the description field. However, in tickets with lots of transfers, field updates or workflow manipulation the activity log is filled with info, which while helpful in tracing the history of a ticket, are not nearly as frequently needed as reading the comment history on the ticket. This extra clutter makes it hard to find the important entries.
Need a method to filter the activity logs to show only entries that have user comments. Currently the only way I know of to find these is to look for entries where action_desc != description. However the SD interface does not let me compare them to provide a new filter mechanism.
