The default way to set up copy&paste with jstree as described in the documentation is easy enough and works well, but only within the scope of JavaScript variables context of the loaded page.
Specifically, if I select copy and then paste that will work. However, if I select copy, then reload the page, paste will not work since the data about copy is lost now.
How can I make this work? I guess something will need to be stored and retrieved from a cookie. Where do I find that? Also, is there an existing option in the plugin for this use case?
