It would be really nice to have the FastGridTemplate updated as well. They are normally kept in sync. At some stage they should be refactored and share the same code if possible.

Thanks @syamajala. The main thing I'm wondering about is how we can save the layout per dashboard, e.g. if I deploy two different dashboards using the ReactTemplate will the layout settings for one persist for the other? Do we need to work out some mechanism to hash each application to allow multiple layout persistence. The simplest would be to simply hash it on the application title but other suggestions welcome.

Actually hashing on the URL would make the most sense.

@syamajala Anything I can do to help here?

This should use the url for saving layouts now.
