At least it's W10 GUI dual screen support is pretty good, have you tried KDE5 and let's now guess which screen my window is going to open on next and is it going to span both screens ?
Note this is not an endorsement of Microsoft W10 but more of a kick in the bollocks for KDE devs. FFS it's 2017 and you still haven't sorted out the crap dual monitor windows placement from KDE4. Martin Gräßlin pull your finger out, compiz has had this right for years.
