When reviewing a Process Map, it would be useful to see the Inputs/Outputs of a Linked Process without having to navigate to the process itself, as I don't necessarily want to see the whole process, but just want to understand what the process requires (inputs) and what it will give me (outputs)
For example, today when you click on the "Triggers and Inputs" label on the Process Map, you see a modal containing the Triggers and Inputs. When you click to a Linked Process it opens a new tab and takes you to that process. As a middle ground solution, we could when you hover over the "Linked Process" to show in a similar model both the "Triggers and Inputs" and the "Outputs and Targets".
If you struggle for space you could consider only showing the names of the Inputs/Outputs on the new modal rather than the full context.
