> but moving/resizing windows is still very painful

Press alt and drag inside a window. Left mouse for moving, right for resizing.

I think GP was talking about limited snapping functionality not resize itself.

Those functions were expanded in Windows 10 lately too.

I haven't checked xfwm4 4.14 yet though. If these functions have been enhanced, excellent! If not, it's worth a request.
