As good as today's development tools are, they still occasionally need a bit of tweaking for developers' particular needs. Thoughtsmithy has long taken advantage of the extensible nature of development tools where it exists, and has striven to provide plug-in solutions that further extend the power of a given tool. For instance, two of our favorite tools, TestComplete by AutomatedQA and ModelMaker by ModelMaker Tools have robust plug-in architectures and can therefore be improved and strengthened. Some of our plug-ins for these tools are available for free download.
