Extensions
The 'Extensions' area of Tab-List Tools occupies the upper-right third of the screen. If the Extensions area is not showing, click 'View > Hide Extensions' or 'View > Hide Tools' in the Menu Bar, or press 'Control+Shift+E' on your keyboard.
The Extensions area contains five pages, each of which is accessed by clicking the relevant tab at the top of the Extensions area:
Scratch Pad - Similar to the system Clipboard, but can be examined and edited. Used for Smart Cut, Smart Copy, Smart Paste, and Smart Delete commands.
Favorites - Store your favorite files here for easy access, pinning and sorting. Favorite files maintain their Bookmarks between sessions.
List Builder - Create large lists from a number of small ones. Includes hierarchy checking for file compatibility.
Directories - Easy way to access files on your computer. Add files to Workspace, ScratchPad, Favorites, or List Builder.
Tree Viewer - Visualize any tab-indented list as a hierarchical tree. Includes full error-checking. Add Bookmarks from any node.
