As I said before, I'm a big fan. I do wish there was a sister project that was intended for a higher level of detail. PlantUML has explicitly stated in some forum responses that it intentionally limits your ability to place elements exactly where you want them. I totally understand their decision, and I greatly enjoy using it for its intended use cases. There just isn't really anything that comes close to the practicality of PlantUML for more detailed diagrams, and I feel like PlantUML would be the best starting place for such a tool. The creator of PlantUML is working on translating graphviz into a native form to eliminate the dependency for PlantUML use. Once this has been done, it would open up even a whole new world of possibilities (graphviz does allow a bit more specification of element locations).
