Feature request for Crosswords for iPhone

I'm loving Crosswords for iPhone, but I have a feature request which I've seen in other crossword apps - an anagramming tool, perhaps under "hints". This is a common type of clue, and anagrams are easy to work out on paper but hard because there's no "scratch pad" utility. Here's what I'd like to see: under hints, select a clue and hit "anagrams". this brings you to a box that's the right number of letters of the clue, which you can type any letters into, and then hit a "scramble" button, which will rearrange all the letters in the box randomly. Scrambling letters like this helps jog ones mind in figuring out anagrams. Ideally, one would be able to "lock" certain letters so that they are not scrambled when the "scramble" button is hit. Thanks for thinking about it...
