On the Mac platform, the race is well under way for the title of ultimate info gleaner and organizer. What appeals to me about InfoManager is that it's small, always on, unobtrusive, and easy to figure out and use. It works like a digital clipping service, in effect supercharging the Mac's built-in clipboard feature and letting it save many different items at the same time. What you see on the screen is a small window, which you can reduce to a simple bar on top of the screen with the click of a button. You grab and save information by highlighting it and dragging it atop the InfoManager window or assigning keyboard commands to do the same thing.
Information is saved in a text file.
With InfoManager, you can store information in a generic file called storageboard that works as a digital bulletin board. And when you've forgotten where you've filed away that critical name, you can use InfoManager's powerful search feature to find it, checking by keywords, strings, or dates, for instance. InfoManager also lets you date, index, and annotate saved information. I find this last feature is especially useful since I always forget why I saved something in the first place. It provides you with a variety of useful ways to organize information on your Mac and information from the Internet.
