I am currently using the Exadel JavaFx plugin and I'm glad that it exists as an alternative to using NetBeans. It's still needs work, but until now it looks very promising :)
I spotted a bug related to code formatting: when the code that needs to be formated contains !=, the formatter inserts a space between the ! and the =, so the resulting code doesn't compile anymore. I have to go in and delete that space in order to make the code compile again. It's not a major thing, but it is a rather annoying bug.
Try testing this using the following block of code:
var a = 0;
var b = 1;
if (a != b) {
//do something here
}
I'm using version 1.3.3.N19 of the plugin.

I'll see if we can fix it in 1.3.4.
