With RPE 2.1 web services, a template can be marked as a snippet when a template is tagged with snippet-XXX. XXX will act as a snippet group name when used from RPE Studio.
When RPE Studio is configured to use 2.1 web services, the Open Template dialog lists the snippets under it’s own group and the palette view again shows the snippets under the snippets group.
The same snippet group name could be used for more than one snippet and a single snippet could be part of more than on snippet group. The open template dialog and palette snippets will be list the groups accordingly so that the same snippet could appear under more than one group.
