Haroopad

Haroopad is cross-platform running on Windows, Mac, and Linux with a focus on an identical experience across them all. It is fully-featured, uses split-screens, supports many languages and color highlighting, Vim key-binding, fenced code blocks (with highlighting), GitHub style syntax, tables, multi-markdown (underline, superscript, subscript), audio/video embed, math, and more.

You can switch viewing modes between viewer, editor, or both in split-screen. The styles of both viewer and editor panes can be changed independently.

Haroopad starts with vanilla Markdown, but adds its own “Haroopad Flavored Markdown” to support special features such as text highlighting and writing a table of contents. It also supports some GitHub-flavored features and various other tweaks like ignoring HTML (or not), and an occasionally helpful auto-completion option.

This project is still in Beta, with some of the documentation in Korean. There is a small learning curve with some of the extra Markup, but it aims to be fully-featured.

The program is free but does have the occasional nag to donate.

There are many interface styles to choose from, as well as export CSS options. You can enable Markdown folding as well. This interface may be the most editable of them all as far as styling your view and exports.

In this screenshot you can see the collapsible syntax help, as well as the text folding gutter.
