…Or maybe if you finish a message and you want to proof read especially for people like managers who deal more on professional kind of messagings. Just my thought but I’m sure theymos have his reasons for keeping it and I think it does exist too on other SMF websites, especially ones with kind of similarities with the forum.
Preview is only meant to show how the text looks when BBCode tags are applied.. If no BBCode is used, the preview is exactly the same as the written text.
If it’s only for preview, then it shouldn’t be saved in drafts. I’m not sure why it might have been hidden, which is why I’m asking. Personally, I don’t see any harm in having it, since the message is already available in the draft.
