LyX has an option "Open documents in tabs" in Preferences > Document Handling.
As far as I can tell, disabling this option causes LyX to open different documents in new windows, but grouping files belonging to the same output document into the same window into tabs. Is it possible to detach such tabs into a new window? Is it possible to open each FILE in a separate window? === The purpose === I am sometimes working with long documents where I'd rather split even one document across multiple windows, e.g. in order to keep a section, which I am referring to, opened on a second screen. In such cases having more than one window per document, or even displaying the same file in multiple windows at once, would be useful. Basically I am trying to use windows to recreate an equivalent of spreading out notes on a table. - Klaus
