I realize it's a pain to support multiple languages but it sure would be awesome if I could put mermaid and d2 diagrams in documents instead of having to start from scratch in the Canvas, even if it's not exactly from scratch (eg AI). Embrace the OSS. I'm not paying Eraser.io for proprietary formats that reinvent the wheel. I'm paying Eraser.io despite them because it delivers the value that I need. That especially means the Team sharing features and multiuser editing. Compare that to Miro which has more features but is even more of a walled garden -- as far as I know, it doesn't even work with Markdown. I don't want products like Miro in my life because I care about the long term viability of my documents.
