Why is it so hard to find a decent UML diagram tool for Linux? Dia is difficult to use. ArgoUML's class diagram is okay, but I can't for the life of me figure out how to add a type to objects in the sequence diagram. And it's unhelpfully weighted down with namespaces, named collaborations, and packages. I don't care about that stuff, I just want to draw a simple diagram.
Visio isn't that hot either, but it used to be, before MSFT got their mitts on it. Why can't I have something like that? I suppose it's because I haven't written it for myself yet.
