Firstly: hats off! This is a GREAT addition.
1) Several objects that had been deleted from my diagram made their way into the autogenerated code anyhow.
2) The code style preferences that I have set for Eclipse in general aren’t maintained anywhere in the UML module.
3) Why does the usual anti-aliased look of Eclipse and MyEclipse not work in the UML module?
Again: hats off!
