With the enhancements to the navigation of 4.0, the ID is now static in the summary view when viewing other areas of the constituent record. Also an additional option is to configure the display name to include the lookup ID.
I feel like BlackBaud missed the mark on this enhancement. Because when I click on a specific plan or gift for example, the summary view goes away, and the lookup ID also disappears with it. That means I have to click out of that view in order to copy/ paste the Lookup ID for reference.
