Nomo - A free, open-source Markdown editor for Windows and macOS

I started building Nomo to give people who enjoy Typora-style editing another free, open-source option. Switch between WYSIWYG editing and Markdown source mode. It supports headings, lists, tables, code blocks, math formulas, Mermaid diagrams, and quick insertion tools. Nomo is still evolving.
