I have always used & liked Multiple Desktops. I’ll admit, I may have this wrong so just bear w/ me a moment. Initially, could not move items from one Desktop to another. I really like it when that ability was introduced. However it only applied to Universal APPs (@ least, that’s how it seemed & fit w/ the understanding I had)… recently, (not sure why I tried, again) it IS possible to (also) move browser pages. Whether, did it & I wasn’t realising or ‘now’ doing it, not w/standing, it is a terrific Feature.
Cheers,
Drew
