There are few applications that I've used as frequently over the past few years as Brett Terpstra's Marked app, now in its second version, Marked 2. In addition to the obvious function of previewing Markdown documents, which I author in TextMate 1, Marked 2 has a few lesser known functions that I really love:

  • Display table of contents for your Markdown document using a <!--TOC--> shortcode.
  • Visualize word repetition
  • Validate all links in document

None of these are especially earth-shattering, but the abundance of nice features like these make Marked an absolute joy to use -- even a few years after I first bought it.

  1. The cool kids all seem to be on Sublime Text, but inertia keeps me in TextMate.
