Is there a means of navigating to a specific fragment in the backstack?
Say, for example, you have fragments A-Z. You've opened fragments A, B, C, and D. You could go back to B by calling close(2);
This works well enough, but what if you have an unknown number of fragments in the backstack? Like if you're sitting at fragment Q or S, and you want to go back to fragment B, is there any method you can call that would pop fragments off the backstack until you reach fragment B?
