A lot of the BPs that I work on have completely different forms and names, but the process has a lot of the same tasks. It would be useful if we could create templates that could be saved and loaded into the Process Modeler. Another idea would be to export and import just the Process Modeler instead of the entire BP.
EDIT: After thinking about this a little more, it might make more sense to make a snippet that could be saved and then inserted from a menu option in the Process Modeler. So I could create certain tasks in the Process Modeler, select those tasks and have a button to save those tasks as a snippet and name it. When I'm working on another BP and need that snippet of tasks, I could simply choose it from a snippet menu and it would insert into my current Process Modeler.
