DTP Tools has announced the release of History plug-in 2.2 for InDesign and InCopy CS-CS3, allowing reversion to prior document states. The tool's undo capabilities are not limited to current work session and changes can be undone years after they were made. The tool can also be used for version management, keeping all document versions within one file, saving storage space and bandwidth. In addition, selected versions can be saved as separate files, or exported in batch, and documents with multiple versions can be safely edited without the plug-in. New features include a keyboard command that opens the various versions in a new document and integration into the new DTP Tools system for easier activations and update management. The tool is priced at $40, and a 14-day trial is available.
