Brett Terpstra has released Marked 2.3, which sandboxes the Markdown previewer in order to bring it to the Mac App Store. While Marked 2 replaces the original Marked app in the Mac App Store, Marked 2 is not a free update — though it is on sale for $9.99 for a limited time (both from the Mac App Store and the Marked Web site). The update now supports GitHub Flavored Markdown for the app’s Discount processor option, preserves bookmarks across refreshes and style changes, adds highlight navigation and highlighted word counts, fixes a problem with reading the most recent file in a folder, improves handling of unreadable and renamed files, and fixes an issue with initial file monitoring when opening in an external editor. Because Marked 2 is sandboxed, previously opened documents may require new permissions. Marked 2 doesn’t currently support OS X Yosemite, but Terpstra promises it will be added soon. ($9.99 new on sale for a limited time, free update, 16.7 MB, release notes, 10.7+)
See All Your Books in iBooks
The iBooks app for iOS lets you assign your books to different collections, but does not have any obvious way for you to see all of your books, regardless of the collection you have put them in. There is, however, a workaround that can show you just about all of your books at once: reveal the search field at the top of any collection in iBooks and type a single space into that field.
With this search, iBooks lists all of the books that have a space either in the title of the book or in the author's name. Other than the rare book that has a one-word title and a single-name author, you end up with a list of all of your books.
