<!DOCTYPE html>
<!-- Proof of concept of running multiple instance of cool.html
at the same time (each one in a different iframe).
To open the first document add the path into the input and click
open. That will open an iframe containing the document as well as
adding the document name to the left side menu.
To open another document press the 'Add new document' link, which is
the first link on the left side menu.
To switch between the documents click on their names on the left side menu.
That will keep the other documents opened, but not in focus.
To test this, do 'make run', and then in your browser open:
https://localhost:9980/browser/dist/multidocs.html?file_path=/opt/libreoffice/online/test/data/hello-world.ods
