New Feature in MS Project 2019

In MS Project 2019 you no longer have to remember the ID of the task you want to link to. Instead, when you select a cell in the Predecessors column, and then select the down arrow, you'll see a list of all the tasks in your project. The task hierarchy and order matches your project exactly, making it easy for you to scroll to the right task and then select the check box beside it. You can also select tasks from the same kind of drop-down in the Successors column.
