The “+ New Topic” button is used in two locations with two different meanings.
The main one makes sense, because when I click it, I get to start a new topic and type in the content. However, in the area where I’m working on the new topic, there is another button called “+ New Topic”. If it worked the same way that the first button worked, then I would get a new blank area when I click it, so I hesitate to click it, though I know it is probably the “Save” button.
I suggest that the second “+ New Topic” be changed to “Save” or “Save New Topic” or “Start Topic”.
