Gallery — Markdown Textarea Toolbar

A small addition to the textarea.
Not willing to be a WYSIWYG editor, it's just a helper.

Works like this:

1. Select some text.
2. Click a button.
3. Markdown syntax is added to selection.

Lorem ipsum dolor -> Lorem **ipsum** dolor

I'm happy :)

Already fixed the margins of the blockquote and lists.
