jGRASP integrates the Control Structure Diagram (CSD) seamlessly and unobtrusively into source-code editing for Java, C, C++, Objective-C, Ada, and VHDL. The CSD is a control flow and data structure diagram that fits into the space normally taken by indentation in source code. Its intention is to improve the readability of source code. The CSD also enables source code folding in a meaningful way, based on code structures. jGRASP provides lots of editing features, an integrated Java debugger, UML dependency diagrams for Java, configurable colors and font size, and click-to-error for compile and runtime (Java stack dumps) errors.
XShelf is an application that enhances Drag and Drop operations in MacOS X by providing a shelf where drag-and-dropped items (such as files, text, or URLs) can be stored for later use. Thus, not only can Drag and Drop operations be "paused", multiple operations can be in flight at once. It is the spiritual heir to the NeXT Shelf.
MagicHat is a programmer's research and reference tool. With MagicHat, you can navigate through a Cocoa's application programming interface (API), review the declarations of language elements such as methods, functions, and constants, and retrieve relevant passages from the Cocoa developer documentation. MagicHat helps you unravel unfamiliar code, whether building blocks from the Cocoa software kits, programming examples, or programs written by your own development team.
CHDecide (formerly known as iDecide) will ask you to estimate how likely you are to succeed with an option, how much it's worth for you and how much it hurts if you fail. It will then compute which option is expected to give the most happiness. The program uses the expected-utility theory to make predictions of which option you should choose. You might think that you don't need a program to make your choices, but research has shown that humans are surprisingly bad at picking the most logical choices.
