Posemark
写的是 Markdown，
看到的是排好版的文档
Write Markdown.
Read a finished document.
Posemark 是一款所见即所得的 Markdown 编辑器。标题就是标题，表格就是表格；光标移到哪一行，那一行才露出 #、** 这些标记。
Posemark renders Markdown in place as you type. Headings look like headings, tables look like tables — the # and ** markers only appear on the line your caret is on.
支持 Windows · macOS · Linux，界面支持简体中文与英文Windows · macOS · Linux, with an English and Simplified Chinese interface
