Are you trying the same Mark Text app (https://marktext.app/ https://marktext.app/ , https://github.com/marktext/marktext https://github.com/marktext/marktext)? Here is a screenshot I just took, trying out things: https://i.imgur.com/bvE0FyM.png https://i.imgur.com/bvE0FyM.png — it seems to do WYSIWYG just like Typora (which I have used extensively), and in fact I can't find a separate preview mode anywhere. (There is a View→Source Code Mode checkbox that you can turn on if you want to view only the source code for some reason, but that's not the default.) See also the screenshots in the GitHub repo's README (https://raw.githubusercontent.com/marktext/marktext/develop/docs/marktext.png https://raw.githubusercontent.com/marktext/marktext/develop/...). Could you explain the difference you have in mind?
