Ok probably I know it is too much to ask but there are already some opensource UML programs like StarUML that could be exploited and remade for Yii.
I believe that the next time to professionalism for Yii framework is to develop a web-based graphic design where users can create UML to do their work more easily.
UML is a vast modelling language with various kinds of graphs. For start only three basic are needed. Use-Case Diagrams, Class Diagrams and Activity Diagrams. With these you can achieve almost everything.
I know there are many UML modelling programs, but only if your design starts from scratch. All this automation that Yii does, creating Models and Controllers and Views SHOULD be synchronized also automatically with a UML diagram(s) and vice-versa.
So what do you think of this idea? I believe would increase the Yii productivity exponentially
PS1: unless there is already a similar tool out there which I ignore. In this case please send me a link!
PS2: Note that because of the automatic include of classes in the framework it is difficult for UML programs to do reverse-engineer to my code to create the UML that really represents it.
