I tried adding the persist extension and it’s working well so far, though further testing is needed. Currently, it uses session storage, so the data is removed when the browser tab is closed. It uses session storage meaning the data is removed when the browser tab is closed. However, this can be switched to local storage if needed.
I also included the restore event from the extension to ensure the previously selected node is reopened.
