Mou

MacDown is heavily influenced by Mou, and I try to mimic much of its behaviour as much as possible both in UI and the logic underneath, only making changes when I feel that improvement is necessary. Highlights include: highly customisable Markdown rendering, syntax highlighting in fenced code blocks and sophisticated auto-completion. MacDown accepts pull requests on aliases to existing languages, but not new syntax highlighting rules. If you wish to provide additional language definitions and/or themes, please visit Prism’s project page and submit them there. I will include updates from Prism after your pull request is accepted.

MarkdownPad is a full-featured Markdown editor for Windows. Instantly see what your Markdown documents look like in HTML as you create them. While you type, LivePreview will automatically scroll to the current location you're editing. Markdown formatting can be applied (and removed) with handy keyboard shortcuts and toolbar buttons. You don't need to know anything about Markdown to use MarkdownPad! Color schemes, fonts, sizes and layouts are all customizable so you can turn MarkdownPad into your perfect editor. Change the look of your HTML documents by using your own CSS stylesheets. MarkdownPad supports multiple stylesheets and has a built-in CSS editor. The default CSS is beautiful and minimal, and will make your HTML documents look great. Quickly create ready-to-use HTML documents, or simply copy a portion of your document as HTML. MarkdownPad Pro supports multiple Markdown processing engines, including Markdown Extra (with Table support), and GitHub Flavored Markdown.
