a software tool that allows you to capture your thoughts or ideas quickly and transparently into a text centered hierarchy, often displayed in tree-like structure of trunk sub-set branches. This tool is more often used by people who think hierarchically or textually rather than visually. The later group might use a mind mapping software instead, however these tools might be complementary rather than mutually exclusive to some (see definition of mind mapping software)
an application that allows you to store notes in a hierarchical fashion
an application you use to help you organize items of information into a structured or cascading hierarchy that visually shows you the relationships and logical connections between items
a special text editor that allows the grouping of text in section s that are organized in a tree ( hierarchy ) of concept s, an outline
a text editor that allows you to control the level of detail that's visible, and allows you to reorganize text according to its structure
A window that lists the objects, lights, cameras, and other items in a scene. You can use the Outliner to examine the structure and components of the scene hierarchy, display shape nodes, connections, and attributes, select and rename an object, and reorder nodes (that is, change the evaluation order). Contrast with DAG. In other software packages, also known as selection floater or schematic view.
An outliner is a special text editor that allows text to be structured as an outline. Outliners are typically used for computer programming, collecting or organizing ideas, Getting Things Done, or project management. It is generally acknowledged that Doug Engelbart was the first to see the advantages of the expandable-outline user interface paradigm in software.
