Split Panes / Views for different documents

Would be great to have one document open in design view and a second (different) doc in code view, e.g. the CSS or some external JavaScript.

This is very helpful when working on designs. Currently I am using a external editor, but would be great as a native feature of Wappler.

(And, while talking, a tick box „File Watcher“ for documents in design view to reload if the code changes on disc, currently i have to keep the document in Split View to automatically reload changes)
