 - `activateViewportBeforeInteraction`: (default to true), if set to false, tools can be used directly without the need to click and activate the viewport.
 - `autoPlayCine`: (default to false), if set to true, data sets with the DICOM frame time tag (i.e. (0018,1063)) will auto play when displayed
 - `addWindowLevelActionMenu`: (default to true), if set to false, the window level action menu item is NOT added to the viewport action corners
+- `caseSensitive`: an object with filter keys that should be case sensitive, only works on STATIC-WADO backends. By default, all filters are case sensitive. If you want to set a filter to be case insensitive, you can set it to false. Example:
+  ```js
+  caseSensitive: {
+    patientname: false,
+    studydescription: false,
+    accessionnumber: false,
+    '00100020': false,
+  }
+  ```
 - `dangerouslyUseDynamicConfig`: Dynamic config allows user to pass `configUrl` query string. This allows to load config without recompiling application. If the `configUrl` query string is passed, the worklist and modes will load from the referenced json rather than the default .env config. If there is no `configUrl` path provided, the default behaviour is used and there should not be any deviation from current user experience.<br/>
 Points to consider while using `dangerouslyUseDynamicConfig`:<br/>
   - User have to enable this feature by setting `dangerouslyUseDynamicConfig.enabled:true`. By default it is `false`.
