Hello i has a suggestion idea about adding a feature simillar to wikipedia sandbox article.\\

What is Sandbox Thread/Draft Thread?
Each user have its own 'Sandbox Thread/Draft Thread' which only they can see and have access.

How Sandbox Thread/Draft Thread going to work?
User can use draft thread feature to save, previewing and working on the threads before posting it to public.

And also have ablity save the draft thread and work on it later, i think this feature going to be useful for user who frequently write a thread
