Tocdown - vim plugin displaying headlines of markdown files

When you are writing a tons of documents in markdown with many headings and you want to get an overview about all the headlines you have, would it be very handy to have shortcut in Vim to simply give you a structured representation of all the heading you have in your large markdown file?<p>The great taglist.vim plugin solved the problem already for variables and functions of many different programming languages but not for plain markdown-files. That's why I wrote tocdown.
