The font rendering on Intellij is horrendous and makes you want to gouge your eyes out. This is because is uses Swing. In order to make this not completely horrible, you’ll need to install tuxjdk, which contains series of patches to OpenJDK to enhance user experience with Java-based and Swing-based tools. I also recommend installing the Monokai Sublime Text 3 theme.

If you install the Lombok plugin, then you’ll also need to set: Settings > Build …. > Compiler > Annotation Processing > Enable Annotation Processors
