It's a bit weird to drag things onto my 4k TV through HDMI and try to track my microscopic mouse pointer to the tiny window to maximize my video, but otherwise works well. I suspect I could fix that in settings somehow though.
KDE has a similar feature: When you hold Ctrl+Win, it will draw revolving circle segments in black and white around the cursor to allow you to find it. It looks like this: https://imgur.com/a/67wfI (You'll have to imagine the cursor inside these circles. My screenshot utility won't include it in the image for some reason.)
