Globally disabling finding Non-code usages in Intellij Idea

This isn't a global setting, but will help address the slowness: in the "Project" panel, identify directories in your project that contain large non-code files, right-click select "Mark Directory as>Excluded" from the menu.

Myself my project directory contained a 'log' directory, plus other directories containing many generated files, and a reports directory containing Junit and checkstyle reports etc. After marking these all as excluded, the Find Usages function was much faster yay.

Unfortunately, the ability to "permanently" set find usage options was changed. The "Find Usage Settings" now resets each time. :( I recommend you vote for and comment on these issue reports:
