I’ve just forked an old abandoned plugin project created to make Eclipse go fullscreen. Originally, the plugin maximizes the usable space by hiding everything but the editors and navigator — which means hiding even the status bar, making it really hard for developers to use.
The single available option was to show/hide the Menu Bar, which is useful for RCP apps. But for IDE usage the status line MUST show up (it’s impossible to debug a stacktrace without knowing which line you are, for instance). My buddy Robson is a packager of ArchLinux and they were facing this issue with Eclipse, so he asked me to fix it.
Get the plugin
You might use Ctrl+Alt+Z to toggle fullscreen, or at Window->Fullscreen
You can choose to hide or show Menu Bar and Status Bar in Window -> Preferences -> General -> Full Screen
