Extensions
For the PoIC manual I introduce an idea of “Extension” according to a suggestion by contributer. In this analogy, the Extension is like a “plug-in” or “add-on” for the Mozilla FireFox. A “System Extension” for the Mac OS (pre OS X) is also easy to understand.
I shape up the PoIC method as possible, and add Extension chapter. Now the PoIC method gives fundamental part only : Four Cards, how to write, and chronological order.
Because of it’s simplicity, we can customize the system as we like. For example, Chross Reference can be interpreted as one of such Extension.
For productivity, life, education, research. Many extension would be possible. Some people already reports such Extensions ; how they combine their own way and the PoIC. Perhaps the Extensions might be a state of experiment. But anyway, it is good to know how people incorporate the PoIC actually in their life :)
