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)
Arrange Icons on the iPhone/iPod touch Home Screens
Unhappy with the arrangement of your icons? You can move them around as follows: First, hold down on any Home screen icon until all the icons wiggle. Now, drag the icons to their desired locations (drag left or right to get to other screens). Finally, press the physical Home button on your device. (Unlike earlier releases, iPhone Software 2.1 doesn't move just-updated apps to the end of your Home screens, so your icons should be more stationary once you've installed the update.)
Remember that you can replace Apple's default icons in the four persistent spots at the bottom of the screen with your four most-used apps!
