A "WYSIWYG like" editor is currently in progress (next big update)
I don't want to go full richtext mode a la LibreOffice writter, it will be something similar as Marktext instead
You will still see the Markdown tag (e.g: the "#" in your heading) but with the possibility to style them in a way that make them pretty much dissapear when your note editing that part, and some nice color and font size for the important part, that would pretty much mimic the preview style ;-)
