A JetBrains IDE plugin supporting the EditorConfig standard
General usage instructions
Simply put your .editorconfig file(s) in place according to the instructions at editorconfig.org site, and the plugin will enforce them. EditorConfig settings will silently override the normal settings configured in the IDE for all files controlled by EditorConfig. That is, if your IDE's settings say to use 4-space indents in Java files, but your EditorConfig settings enforce 2-space indents in all the files under the "src" directory, then hitting tab will insert 2 spaces on Java files in "src", but 4 spaces in all other Java files in the project.
