1- Allow files "not saved" - "Untitled-1". They are moved to new windows, not only files and have already been saved.

2- So there is no conflict between the files, remove the number from "Untitled", or automatically rename to new sequence numbers when we moved to a new window that has the "Untitled -'x '."

3- By dragging the tab out of the tab bar to open in a new window. This is not possible.

This may require quite a bit of work to find out that the drop happened outside of the window, I am not sure this can be easily detected but I can give it a quick try.

I could not find a solution to detect that you drop outside of the window other than maybe looking at the X/Y coordinates and then checking if they are within the window, which is super ugly. Given that, I think I would rather not want to add this until there is real support for better cross-window DND.
Also: this does not help with the case where the drop operation was not successful on the target. I think the real solution would be to somehow include the originating window in the dragged URI and in the target window send a IPC message over to the source if the drop was OK and only then close the editor.
