Anxiety: Slick bare bones task manager
Tuesday, December 11th, 2007
Anxiety is a new and well-crafted “no frills” task mananger for Leopard that manages a list of your to-dos and syncs them with iCal and Mail.app.
Personally, I like the big, fully-featured approach to task management (OmniFocus, iGTD
, etc), but not everyone needs all the bells and whistles.
If these big hitters are not for you, then Anxiety is well worth a look. As the developer says, “With a tiny desktop footprint and clean minimalist aesthetics, the application is simultaneously small, beautiful and effective”.
It presents a simple list of outstanding tasks, which can be displayed and hidden again by clicking on the app’s Menubar or Dock icon:

When it has focus, hitting Return brings up a pane to create a new task. Tabbing through you can quickly enter the task and assign it to the calendar of your choice. Once it is created in iCal, it is soon synced into Leopard Mail as well.
Double-clicking on a task in the list opens the to-do in Mail or opens the task’s Edit pane in iCal (you can set this in the app’s Preferences).
Checking the box on the left, completes the task, which turns a violent green and then disappears.
Anxiety’s Preferences allow you to determine whether it displays tasks by individual calendar or in a unified list, whether the icon is displayed in the Dock, Menubar or both, and various display options:

Anxiety is freeware (donations not refused) and is available - along with a comprehensive list of its many virtues - from the developer’s web site

I’ve been using Leopard for long enough now to collect five tips that save me time and effort. Let me pass them on to you.
Now that I am a Dean and need to set and manage budgets, I need to do sums more than ever before. A nice new feature in the Spotlight window, does your sums for you.
Hovering the mouse over a name or details of an event in Leopard Mail activates Leopard’s Data Detector and produces a drop box with the option to add it to Address Book or iCal. 
It adds a menubar item with the date and/or the time, replacing the default System date/time display. Clicking on it opens a drop-down box with the current month, and a list of events and tasks for the day which can be toggled on and off. 
A keyboard shortcut pops up a “heads up display” for creating a new task. I find it easier to use that the list of to-dos in Mail (subject for another post, but why are Mail’s to-do features so underdone?!).
