It'd be integrated with the preview page..
I like the livejournal thing of highlighting the words it thinks are misspelled..
I think there are a few key elements:
- show misspelled words & reccomended replacements
- be able to see both reccomendations and the text where the occurs at the same time
- have a convenient way to chose a suggested replacement (or type a new one) and apply the correction
One way might be to have a column on the side with the suggestions. Another way might be to have misspell flags be links to a correction popup or frame. I'm not sure what would be best.
