TreeTime

One Tree#

A tree sorts information into boxes. It orders items by categories and sub-categories. Like country / area / town / district / street for places. Or year / month / week / day for events. Or company / branch / department / team for employees. TreeTime is a big, general purpose tree editor.

Many Trees#

Most things belong in different categories at the same time. Trips you make have a destination (country / town) and a time (year / month). Science articles have a topic, and a journal, and an author. Your relatives have birthdays and places where they live. TreeTime is an organiser that uses multiple trees.
