Webin has released ReadKit 2.4, a major update to the RSS client and read-later app with improvements to keyboard navigation and the introduction of a new sharing service. With version 2.4, most keyboard shortcuts can be customized under the Shortcuts tab of Preferences (this Webin blog post offers an explanation of the new shortcuts). ReadKit also adds support for the Buffer sharing service, which enables you to share links to your social media connections immediately or schedule them to appear throughout the day or week. The update also adds the capability to highlight code blocks, brings more granular preference settings on a per-account basis, adds a customizable sharing toolbar, improves sync speed of the built-in RSS engine, and improves compatibility with OS X 10.9 Mavericks. Unfortunately, ReadKit 2.4 drops support for 10.7 Lion. ($6.99 new from the Mac App Store, free update, 4.0 MB)
New Documents in Snow Leopard's TextEdit
In the Snow Leopard version of TextEdit, you can now create a new document by Control-clicking TextEdit's Dock icon (when it's running), and choosing New Document from the pop-up menu. This isn't a major feature, of course, since you can also just press Command-N while in TextEdit, but consider Control-clicking other applications' Dock icons to see what functions they might make available.
