Hey @zsviczian — I'm Brett Terpstra, developer of Marked 3, a live Markdown previewer for Mac. Given how deep you are in the Obsidian + Excalidraw ecosystem I thought it might be worth a look: markedapp.com. Happy to send a review license if you're curious.
Marked QL is featured in the @ProductHunt newsletter! Check out Marked QL at markedapp.com/ql (new version coming soon with TOC and Quarto support, plus handling of non-standard UTIs like iA Writer and TeXShop create)
Coming in the next update: Quick Actions Palette! Pop it up with a shortcut and have keyboard access to all commands from the main menu, gear menu, and preview shortcuts.
