TLA Systems has released PCalc 4, rewritten from the ground up to resemble its iOS sibling. The latest version of the powerful Mac calculator includes a number of new features, such as the capability to show multiple lines on the display; a “ticker tape” option to show a history of recent calculations; editable user functions and conversions that sync to iOS and other Macs via iCloud; smart searching for conversions, constants, and functions; enhanced AppleScript support; and more. PCalc 4 requires OS X 10.8 Mountain Lion and is a free update for both Mac App Store users and those who purchased PCalc 3 from Kagi after 1 April 2013. It’s now being sold exclusively through the Mac App Store. ($9.99 new on the Mac App Store, free update)
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.
