Check this free markdown WYSIWYG editor https://marktext.app/. I guess it is inspired by Typora which is the first I saw. It is very impressive. Not sure about the image drag and drop. That is app specific.
I wished we had that for ASCIIDoc because it looks more powerful than the half backed Markdown.
