b288 - addedValues can now track the usage of variables, forms, queries and reports in macro calls within manila templates and optionally, messages. A new preference, Track usage in messages, in a new panel section enables this checking. Setting this option adds an overhead to message creation an editing, as addedValues must examine the value of any string valued variable that might contain a macro call. Sensible use of the 'value must be' variable attribute can decrease this overhead as the only value that needs to be checked is "Any String". For most purposes you do not need to allow html tags (and macro calls) as components of the value of a string variable, so 'No HTML' is a better choice. If an entity is in use within macro calls it addedValues will prevent the entity from being deleted and report the places where it is in use.
