I used Rational-Rose and StartUML in the past years. Sometime ago, I accepted a training about modeling, and noticed the tools is UML. Now, I tried to use it modeling my system, and find the help-document in the official-website is incomplete and the tool is not good as the website claimed. For example, the function undo/redo is not supported, and some issues are not updated for a long time.
Has ArgoUML abandoned development for the next generation?
