0. To clear the canvas, you can select all of the components by pressing Cmd + A or by holding down Shift and dragging a selection box around them. Then press Delete.
1. Created templates are stored in the flow definition. If you create a template, you can verify this by unzipping the conf/flow.xml.gz file and examining the XML. You will see the template definition.
1. a. You can export the template through the UI by going to the global menu at the top right and selecting Templates. Then click the “Download” button on the right for the individual template you wish to export.
2. Template definitions are static — once you create a template, modifying the components on the canvas does not modify the template. To “update” a template, you repeat the initial process and create a new template. I’ve included screenshots of creating a template, modifying the flow, and then exporting the updated flow as a new template.
