One of my favourite settings in IDEA is to turn on the ‘Add unambiguous imports on the fly’ option.
With this on, if you type a class name, and that class is unique in the project libraries, IDEA automatically adds an import for that class. No need to stop typing to press ALT – ENTER.

So, I updated to IDEA 7 and found this wasn’t working anymore. Even more annoying, I couldn’t find this option in the settings. Turns out this setting has a new home.
In IDEA 7, it is has been moved to Settings|Code style|Imports.
