Thanks @MattWho , actually found a way to filter/search process groups by name using the Summary option in the top right menu. This is very useful to find all the ETL pipelines once we give proper names and then by entering a part of the name we can show all matching Process Groups. Being a newbie I am trying to compare Streamsets UI to Nifi UI so I can work the same way. Streamsets provides an initial list of all ETL pipelines to filter by name etc. I guess if just after Nifi login if we saw two links: Summary and Canvas then users can click intuitively on the summary screen and review all their Process groups and click on specific PG they want to work with. This would make it similar to other ETL tools like Streamsets.
