Hi Ambi,

you CAN actually have multiple critical paths in OP 2.0! Any milestone can have a critical path traced back from it. You can check this out by creating a milestone, and then looking at the new Milestone Inspector which is right next to the project Info inspector (it has a diamond milestone icon). There you can turn on and off various critical paths, and change the color they show in, as well as adjust slack for each one.

edit: Here's a screenshot of what I'm talking about, hope that helps!
