Zoomie is a small extension that makes window Zoom boxes more convenient.
With Zoomie, the mouse pointer moves WITH the window, staying inside the box where it's ready to immediately click again.
This sounds like a very small thing, but I discovered when I tried it that Zoomie is a very nice feature! And besides, it's only 4k and it's free! Give it a try and let me know if you like it.
