IntelliJ IDEA code reformat options

Question

When I press Ctrl + Alt + L, IDEA removes unused import. I want to turn this feature off, leave the unused imports there. Where can I affect this setting?

Answer 1

First check:

File | Settings | Editor | Formatting | Show "Reformat Code" dialog

Then when you hit Ctrl + Alt + L pop-up dialog will appear.

Uncheck Optimize imports and check Do not show this dialog in the future. Hit Enter or click Run. That's it!
