title: A way to use UML Diagrams between Intellij IDEA Ultimate / CE and other IDE
body: <p>I find IDEA being by far my favourite IDE. 
  The only problem i am seeing is that Ultimate editions HAS UML Diagrams, the community edition doesn't have that feature (Code Navigator plugin isn't working on last idea versions as far as i know)
  I work a lot with UML in all the processes from engineering to deployment and i can't let other users force switching to Ultimate edition, plus not all using IDEA as their IDE.
  I am looking for a third part UML forward and reverse engineering capable that suits my needs of cross-compatibility</p>
