Working great so far! Thank you very much!
Found some detail in Obsidian Roundup:
Insider 0.15.0 is a pretty major update that brings coveted new functionality: the ability to create multiple windows of the same vault. A few months ago
@javalentwrote a hacky plugin to allow this, but having it in core allows for a lot more neat tricks, like the window title including the active file name.
Exciting powerful features! Thank you very much!
