HFUiAppkit contains goodies for iPhone developers.  This stuff was developed for use in GroceryList (http://www.heliumfoot.com/grocerylist).  It includes:

adds a second index to UITableView.  In GroceryList we use it like this:  Tap on "C" in the index to reveal a secondary index, then tap on "Choc" in the secondary index in order to select "Chocolate Chips" or "Chocolate Milk".  See Nations.app in the SampleApp folder for an example

to show a Mail message count style bubble with text in it.

Adds the following methods to NSString:
	-(NSString *)stringByNormalizingDiacritics;
	-(NSString *)substringUpToIndex:(NSUInteger)anIndex;
