When I first started using BeOS about 5 years ago I was very impressed with the spellchecker in BeMail. The way it works is a model of elegance. But I was surprised to see that Be hadn't included the same system in StyledEdit.
Now, I see it's working in the Haiku Mail app (if you import the dictionary files from BeOS).
Is there any reason why it cannot be adopted in the Haiku StyledEdit?
Of course, it would need some modification to allow for the different font colours supported by StyledEdit; it can't just assume black and display red for the flagged words...
