I just downloaded Dan Bricklin's latest update for his app, NotetakerHD. I must say that the guy really seems to be trying to add useful features for us handwriting afficianodos.
This latest version has a moveable zoom window which, to my mind, is a sorely needed feature. I no longer have to put my wrist on the very edge of my iPad for support.
I am still hoping that he will add copy and paste to the clipboard as a feature.
But, all in all, it is still one of my top apps on my iPad!
