# TreeLine Features

General
- Stores almost any type of information, including plain text, rich text, HTML, numbers, dates, times, booleans, URLs, etc.
- The tree structure helps keep things organized.
- Each node can have several fields that form a mini-database.
- Several node types, with different sets of fields, can be included in one file.
- The node format, including fields, output lines, formatting and tree-view icon, can be defined for each node type.

Views
- The left-hand view shows an indented, expandable list of titles
- The right-hand view can show one of three views - for showing output, editing node data and editing node titles.
- The right-hand view is normally split to show data from the parent node and its children.
- If multiple nodes are selected, the right-hand view shows all of their data.
- The output view can be set to show indented output from all descendant nodes.
- An upper breadcrumb view shows titles of the selected node's ancestors; the titles can be clicked to select them in the tree.

Navigation
- Find commands can search node data for text matches or for more specific rules.
- Filtering commands show only matching nodes in a flat left-hand view.
- Previous and next selection commands toggle selections to quickly move between parts of the tree.

Formatting
- The dialog for data type configuration has several tabs to easily set all type, field and output parameters.
- Each tree node can be set to a type format independently.
- Formatting information can be copied from another TreeLine file.

File Handling
- Undo and redo commands are available for all modifying operations.
- TreeLine files use a JSON format, with options for automatically compressing or encrypting the files.
- Document templates for new files are preformatted to cover basic needs.
- The formatted output can be printed with parent/child lines, headers and footers.

File Import and Export
- The data can be exported to single or multiple HTML files with optional navigation panes.
- A live tree HTML export creates an interactive view with expandable nodes and a descendant output pane.
- Plain text, tab-indented text and delimited table files can be imported and exported.
- Files from older versions of TreeLine (2.x and 1.x) can be imported and exported.
- Mozilla and XBEL format bookmark files can be imported and exported.
- Generic XML files can be imported and exported, allowing TreeLine to function as a crude XML editor.
- ODF text documents can be imported and exported as outlines.

Linking
- Internal link fields select a linked node when clicked.
- External link fields can be used to open URLs in web browsers.
- Both internal and external links can be embedded into text fields.
- Nodes that are duplicated by cloning show up as separate clickable paths in the upper breadcrumb view.

Data Manipulation
- Nodes can be sorted by title or by predefined key fields.
- Math fields can be defined that automatically calculate their contents based on numerical values in other nodes.
- Numbering fields can be defined and automatically updated.
- A node's icon and output format can be changed conditionally based on its data.
- Cloned nodes (the same nodes with multiple parents/locations) can be created using special paste commands or by automatically matching identical nodes.
- Text data can be spell checked (requires an external program - see the System Requirements section).
- Data can be automatically re-arranged using categories from data fields.

Customization
- There are many options for customizing both general and file-based attributes.
- There are editors for keyboard shortcuts and toolbar commands.
- Fonts used in the GUI, editors and output views can be customized.
- The user interface is available in simplified Chinese, English, German, Russian and Spanish. Translations into other languages are TBD.
