In the GENERAL tab the fields for the name and the component are deactivated. To rename a template you could use the rename button in the templates list.
The corresponding graphomate component can not be changed, because the property set in a template can be only applied to the same component which was a well used to create the template.
The field for the tags can be filled with a list of tags which are separated by comma. The description and the author are free text fields.
In the Created and Changed Fields nothing can be changed, because the Changed timestamp will be updated automatically once the template is saved.
