In general, the dialog seems to open to a set height of ~250px by default which is somewhat unexpected and is too tall for an average confirmation/message but too small for a form. It would be more useful if it auto fit the content length and had a maxHeight default set to something reasonable like 400px so it would fit on an average 1024x768 screen without scrolling. It's a pain/dangerous to have to set an explicit height every time.

This should behave like a normal block element that expands to the content as much as possible. I get worried about setting a fixed pixel height because font sizes and content lengths could very and you really want to avoid scrollbars on dialogs as much as possible.

when you start dragging a draggable with the cursorAt option set, the draggable jumps to the position that puts the cursor in the right place. It would be nice if this were animated.

The events are currently sliderstart, sliderslide, sliderstop, sliderchange. They should slidestart, slide, slidestop, slidechange.
