Tree Viewer
The Tab-Indented Tools program has a built-in visualizer that will display your tab-indented list in the way that your usual program will handle it. To visualize a list, the first line must have zero indents, and be free of Blank-Line and Excess Indent errors.
Visualizing a list is very easy to do: simply load some text to the Workspace, then select the 'Extensions > Tree Viewer' page and click the 'Visualize Current Page' button. If there are any errors that will stop the tool from working, they will be identified.
The resultant 'tree' of your tab-indented list will be shown in its collapsed form in the working area of the Tree Viewer. Click on the '+' node-handles to expand the tree in the direction and to the level that you want. Click on the '-' node-handles to collapse the branch above that node. The 'Collapse' button at the bottom of the page will return the tree to its fully collapsed state, and the 'Clear' button will clear the tree from the working area.
Clicking on a node in the tree will show the full hierarchy for that node in the box at the top of the page.
Right-clicking on a node in the tree gives you more options:
Scroll to Line: Will scroll the text in your Workspace to the wanted line that contains that node, and place the caret at the beginning of that line.
Toggle Bookmark: If no Bookmark is already present for that line in the Workspace, it will add one. If there is already a Bookmark for that line, it will delete it.
Copy Hierarchy to Clipboard: Will copy the full hierarchical string for that line to the Clipboard. You can then use it for other purposes, such as pasting it into a new Workspace window.
