Current Limitation

With many columns we often want to see ex username and email before other less relevant fields. Currently the four system columns appear first and then the rest of the fields have a random? order.

Feature / Enhancement Description

Forcing the columns to be in the same order that is specified in the columnPreference field. All non-mentioned columns can come in a random order in the end.

  apps: [
    {
      columnPreference: {
        "_User": [
             { name: "objectId" } // first column
             { name: "username" } // second column
         ]
      }
    },
  ],

Example Use Case

All dashboard users store their own ordering in localStorage, but I don't want everyone to need to create their own order for 10ths of classes. It would be good to provide a sensible and customised default for all users.

Alternatives / Workarounds

None which I am aware of.

3rd Party References

Start by locating the dashboard code that reads the columnPreference configuration and applies saved ordering from localStorage. Verify that listed columns appear in the configured order, while unlisted columns follow afterward, and add or update the relevant tests if they are found.
