For example, click on a GetSFTP Processor and then choose to show only components that a FlowFile could get to from that Processor. Other components should be either hidden or faded out so that the components of interest are shown.
This would make it much easier to understand a flow that someone else built or a flow that you haven't touched in a while.
Should be possible to show this from a Processor, Process Group, Remote Process Group, Port, or Funnel.
If a Process Group is shown, should be able to go into the Process Group and see only those components reachable from the Input Port that is relevant.
