I conversed with Jon about some of this a while ago, but not all of it.

I pay for and use DisplayFusion in both home and office. Lots of 4K monitors. I have some keystrokes set to move the mouse to any specific monitor, and to move the current window also to any specific monitor, as well as to dim the non-current windows.

I'd like a few enhancements.

1. A better mouse locator than Windows. Windows has the Ctrl-press concentric ring finder, but it would be nice to be able to, at the same time, be more obvious and perhaps dim the other monitors.

2. Move the mouse to wherever the active text cursor is.

3. Use that dimming method to allow different display dimmings by keystroke (custom function), so I can have the screen full-bright e.g. for a game, and then with a keystroke have it lower for white-backgrounded text. (I had a utility that did that, until a year ago when the newest Windows decided it didn't like it anymore.)
