Overall very nice program. Everyone will want somewhat different UI conventions, but here are a few small UI changes that I think would improve the interface a bit. One, it would be great if moving the "cursor" with the cursor keys did not (or at least did not have to) change the direction being highlighted. I would like to be able to use a different key (like the space bar) to switch directions and leave the curson keys just to move the current square. Two, the clue in the drawer that corresponds to the selected word in the table should be highlighted more prominantly than the clue going the other direction. Neither of these issues is that serious, but right now I find the navigation a bit awkward. But still, the ability to download puzzles is great -- well worth the money!
