Brett Terpstra has released Marked 2.2 (Build 822), which adds a couple of new features to the Markdown previewer. According to this blog post, the latest build improves how Marked handles opening external files that aren’t recognized (suggesting to open in a default app instead of just providing an error message), asks whether you want to open links in the current window or a new one, and improves how it handles YAML (the “human friendly data serialization standard for all programming languages”). Marked also now features MathJax configuration updates, syntax highlighting improvements, and a fix for MultiMarkdown metadata like “Base Header Level” and “Quotes Language” not being recognized. A quick update to Build 823 fixes a minor bug. ($11.99 new, free update, 16.3 MB, release notes)
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
