That kind of error was expected. I don't see it as an issue against the rewrite. They kept the stable versions on Zig in case ppl needs stability. Eventually, the errors will get fixed.
Obsidian is by far my favorite note taking app of all time. I always try new ones for specific stuff to see how each can improve my productivity daily, but I always stick with it for all my most important things. This canvas product being opensourced and migrateable is great specially for users that try different things like me.
