Conjure is a sketchbook. It makes mind maps. You can make notes on it. Save links to important things, from specific emails to websites. It's a file organizer. It's a launcher. It's a photo manipulator. It can even use iChat to help you broadcast and collaborate your thoughts with other people. And it lives right on your desktop, so it's always there when you need it. On top of all that, you can have an unlimited number of desktops, and flip between them like cards in a deck.
Conjure lets you create and navigate between an unlimited number of desktops. You can even switch desktops while you're in another application. This way, you can stay focused on the project at hand, while keeping all of your other projects at your fingertips.
And now in Conjure 4.5, you get new tools, tabbed desktops, better DropBox support, and over 20 other new features and enhancements. The One-shot license is still $5.00, while the full license is $25.00.
