Mac app Todolicious by Mustacheware was one of the first Mac App Store-exclusive apps we covered ahead of the launch of the new Store and, overall, an elegant to-do manager for the Mac that makes it easy to jot down tasks with an intuitive keyboard-based panel you can invoke at any time. With the choice of multiple themes and cute sound notifications for completed tasks, Todolicious still is one of the “best new apps” available in the Mac App Store (also mysteriously not featured  by Apple since January 6th).

An update to Todolicious was released today adding a new editing engine and an option to delete completed to-dos, but that’s not what we want to focus on right now. The update is great and adds a bunch of much requested fixes, but what we think is absolutely worth of your consideration is the fact that Mustacheware decided to donate 100% of sales today to the New Zealand Red Cross in response of the earthquake that occurred on February 21. If you buy Todolicious today (February 25), you’ll give your contribution to the victims of the earthquake and, at the same time, you’ll end up with a sweet application on your Mac.

So head over the Mac App Store now, and download Todolicious.
