When user is using JavaFX, NetBeans Java Editor should propose him classes from javafx packages rather than from java.awt package in code completion.
There should be a way to register some preferable packages for code completion per project. For example JavaFX will register javafx package though some SPI and Java code completion will take it into account.
Fixed in jet-main.
Prioritization of code completion items is done automatically based on reference counting.
Integrated into 'main-golden', will be available in build *201203150400* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
