🤷♂️ I used it all the time back around twenty years ago when I still was using a stacking window manager with floating windows. It's all about practice I guess. For me it felt natural initially though.
Also holding down Super and dragging with right mouse button to resize is great.
The entire window is a much bigger click target than the title bar or the window borders (actually each quadrant would be the click target for resizing, but still a lot bigger). Fitts's Law in action.
I don't use it much now that I moved to tiling window manager many years ago, and now a scrolling window manager, because those are mostly controlled with use of keyboard shortcuts. But sometimes I still use this even now. 👍
I guess you could move it to another monitor then hit Super + Up to maximize, or a similar shortcut, if your window manager is a capable one. 😅
