You can customize the spell checking functionality by setting the properties of the UltimateSpell child control.
For example, you can set the MaximumSuggestions property to 3 (default value is 10) to provide up to three
suggestions for each misspelled word. Similarly, you can display the "Show Options..." button on the spell check
dialog box by setting the ShowOptions property to True.

There are lots of other features of the spell checker, which you can customize by setting the properties of the
UltimateSpell child control.
