Hello, @kabeersvohra.
Thank you. I can confirm - this is a bug, issue 37664 in our internal issue tracker.
multi window mode still locked, but in development. it'll be available in close releases
Do you have any update about that ?
It would be very useful to be able to have one window per doc.
I'm interested in an update as well. So far I love this document editor, the only thing that seems to be holding it back it the lack of being able to use multiple windows.
Keep up the great work on this project!
