I have many activity diagrams (about 30 or so)in my project. They are often multiple nested, e.g. from a menü overview to a sub menu and from there in a modul in that an activity refer to another diagram. As a hyperlink function would exist to jump to a needed diagram, it would improve the clarify of the activity flow very much. Because the tree on the left side has grown so much and to find a diagramm which is in a subfolder of a folder for the specific functionality is very hard. At the moment I managing this problem with a path in a text field left or right of the acticvity block. But it's not so productive as a link which would bring you very fast to the needed diagram. 

I don't know how difficult it is to implement this feature, but if you could do that, the productivity of umbrello would grow again and I will get very happy :))

Umbrello is great and I won't miss it anymore. Good work !! Thanks !
