In my project at work, I was forced to do one very painful refactoring, but hopefully, IntelliJ came to rescue! The task was divided into two steps. The first step was about extracting literal into a constant variable in about maybe 200 places. That step was easy by using Replace in Path (Ctrl+Shift+R). The second and final step was about making static imports to that new constant in every class. Making such a change by hand was too overwhelming for me, but expectantly, there is a tool in IntelliJ called Replace Structurally. That tool allows you to replace every import of your variable to be static import instead of normal field import by selecting the option Use static imports
