    A modern, lightweight text editor with a minimalist design

    I have been waiting long enough for a modern Windows 10 notepad app to come before I decided to create one myself. Don’t get me wrong, Notepad++, VS Code, and Sublime are great text editors. I have used them all and I will continue to use them in the future. However, they are either too heavy or look less appealing. There are times that I just wanted to use Windows Notepad for things like writing notes or editing config files. So I decided to create a win32 notepad replacement here and try...

    Inkdown

    Inkdown

    A WYSIWYG Markdown editor, improve reading and editing experience

    ...Almost fully compatible with the GitHub Flavored Markdown standard, while extending the Mermaid graphics and Katex formula, supporting light and dark styles, and somewhat different from other WYSIWYG editors, Inkdown does not pursue complete customization. Its core goal is comfortable reading, smooth editing of Markdown, and document sharing in the simplest way possible. As a document publisher, markdown source code mode is undoubtedly efficient and free, but as a note, it is not conducive to reading. The table element of markdown is not conducive to writing, and the double-column mode is not conducive to focusing, so the Inkdown Editor was developed. It combines rich text with markdown editing habits to help you record daily, and saves it in standard markdown format, which allows your notes to be used anywhere and backed up in any way.
