Is this possible? If not, why not, If it is, there should be something indicating how to do it.
It seems that add topic means save.
I just found the three little dots which appear to open the topic for editing. Is this a standard icon for this purpose? Do we simply assume that people will know?
It also appears that switching back to visual editing gives a preview. I like that. I also see that the add topic button is now a save changes button, which is good and clear.
