We use the process documentation export to PDF and Word from the Process Manager quite a bit and we find the possibility to configure your own templates very helpful. However some of the information extracted can be a bit difficult to read and fully comprehend.
Some information from custom attributes on diagram level is boxed together without line change or other visual marks to distinguish them from each other. I suggest that either all infromation from the attributes on diagram level by default is clearly split by some sort of bullet points, or that you can customize this view in the template. On the element level the information is clearly distinguished from each other by use of bullet points. The same would be good for the diagram level as well.
