I've been using this UML modeling tool for a while now, and I'm impressed with its capabilities. The features are comprehensive, and it's easy to create, edit, and manage UML diagrams. The best part is that it doesn't feel overwhelming, unlike some other tools out there. The user interface is clean and minimalistic, making it a pleasure to use. Highly recommended for anyone involved in software development.
