1. How do I select the font to use? The variable-width default font feels entirely out of place for me with Markdown.
2. This could dearly use integration with Prettier (https://prettier.io) or a similar tool for those of us fussy with formatting details.
3. The lack of Multimarkdown syntax like cross-references (http://fletcher.github.io/MultiMarkdown-5/cross-references.h...) is painful for those of us with elaborate note-keeping. It's doubly painful that Obsidian apparently has its own invented syntax instead of using what's already been around for years and years with MMD.
4. How in the world do I link between files? Nothing I do works, and there's no help document and not even a "copy as link" on the right click menu.
