Flexibits has released Fantastical 1.3.6 with the capability to use natural language to specify a calendar as you type the text of an event (previously, you could specify a calendar by using a forward slash at the beginning or end of your text). Now you can type “calendar [calendar name]” in an event string (such as “record Watchlist podcast calendar TidBITS”). The update also speeds up event updates for Microsoft Outlook users, ensures the details window doesn’t disappear during an active search, and autocompletes two-digit years (where 13 becomes 2013). ($19.99 new, free update from Flexibits and the Mac App Store, 11.2 MB, release notes)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
