If I have understood you correctly, I think your feature request is a duplicate of this one: Fully visual editor mode (WYSIWYG / WYSWYG)
You have requested that there be “only two views”. One of the views you describe does not currently exist in Obsidian, and is the subject matter of the WYSWYG feature request.
The WYSWYG mode seems to be the main substance of your request; if Obsidian had the modes that you want it to have, then you could simply assign keyboard shortcuts to enter those modes, and then never think about it again, right? So, the complaint about the complexity of the available modes seems quite marginal. Unless there is a substantial feature request you have in mind regarding the interface, or the way modes are selected, that is independent of the WYSWYG feature request. But, I don’t think there is.
So, this feature request seems like a duplicate of the WYSWYG request, pure and simple.
