I'm not sure if this has been addressed yet, but I am getting to a place where I would like to have a grouped list, and can be quickly navigated with the indexBar. However, on the kitchen sink example, the index bar doesn't jump to the group associated with the letter tapped on the index bar.
Also, I was hoping to be able to populate the characters of the index bar dynamically based on whether there are items in the associated group. In other words, if there are no items that start with the letter Q, then Q will not show up on the index bar.
Answers to how to do this, and/or added functionality to make this possible would be dreamy!
