Typora is great but it is a jarring experience with all the content hopping around when cursor enters a link or image, the markup suddenly appears, and the current mouse-cursor position is now invalid. This is much higher “cognitive load” to me.
Bear’s Panda editor is a much better target to aim for. For instance, put the URI markup in GUI elements rather than the face-assaulting Typora expansion. Hopefully, the markup can seamlessly accessible to the preview through well design UX.
Recent topical post from the old guard (guy who invented markdown):
the whole point of it is to provide a syntax where the most common HTML tags for prose can be replaced by simple punctuation characters that are meant to be visible to the writer.

As others have mentioned, WISIWYG should be in addition to the purist markdown experience. Personally I would still want the URIs hidden as they really just get in the way. When do you need to see the massive gibberish link (that’s longer than the sentence it is within) to the webpage you are writing about? Especially if you can view said URL with a keystroke.
