+### Custom order in the filter popup
+
+If you have classes with a lot of columns and you filter them often with the same columns you can sort those columns to the top by extending the `columnPreference` setting with the `filterSortToTop` option:
+
+```json
+"apps": [
+  {
+    "columnPreference": {
+        "_User": [
+          {

 # Running as Express Middleware
 
 Instead of starting Parse Dashboard with the CLI, you can also run it as an [express](https://github.com/expressjs/express) middleware.
