Bringing the same precise timing capabilities of its calendar entries to reminders, Flexibits has released Fantastical 1.3.11 with the addition of a due time field when you select Due Date in a task. The calendar app also fixes errors when using iCloud, an issue that prevented Outlook events from updating, a bug that made Fantastical appear partially offscreen when using multiple displays on OS X 10.9 Mavericks, and a potential hang when creating events with invitees on Mavericks. ($19.99 new, free update from Flexibits and the Mac App Store, 11.7 MB, release notes)
Open a Finder Window with the App Switcher
If you don't have any Finder windows open and want to switch to the Finder and open a window in one fell swoop, bring up the app switcher with Command-Tab and tab over to the Finder icon. While still holding down Command, press the Option key, and then release the Command key. You're switched to the Finder, with a new default window open for you.
