This and its sister fork contain the additional features in JDT Core and JDT UI that I find useful but are missing from the official Eclipse IDE. These include:
The bog standard Eclipse IDE:
I can't help with your terrible taste in color themes, but the Content Assist changes are included here!
And there's more!
Content Assist suggests methods from the concrete class before methods from super-classes.
Ctrl-Alt-Left and Ctrl-Alt-Right are like Ctrl-C, Ctrl-V, except smarter.
Clone both JDT Core and JDT UI repositories in Eclipse SDK, import the projects eclipse.jdt.core and eclipse.jdt.ui, make sure the code compiles and export both projects to the current installation.
The license is still Eclipse Public License (EPL) v1.0
