[Feature] Disable all forms of expansion in non-source mode

[izzyreal]

Is there a way to disable all forms of expansion (into Markdown) in non-source mode?

The reason why I want this, is because I'm never interested in any form of expansion in the non-source mode. The hybdrid WYSIWYG + source behaviour that is the result of expansion in non-source mode, is making for a wobbly, slippery, confusing UX. The appearance of the document changes quite drastically based on where the cursor is, and after having used Typora for more than 3 years, I've come to the conclusion that it would be highly valuable to maintain a clear separation between WYSIWYG and source code.

Many thanks in advance for considering this feature. If a more technical specification is needed, or a motivating reproduction of some kind, just let me know.
