Are you Windows user and do you have a huge monitor and moving a mouse pointer to one window to another take a long time?
I believe Vivaldi is a great web browser and I was glad to find a solution there.
bring the mouse pointer to the top left corner of the focused window when switching windows by Alt+Tab.
Actually, I had another motivation to try this tool. I use Sysinternals ZoomIt’s “LiveZoom” on external display.
I hoped the AutoHotkey script could move the mouse pointer to main display without touching anything on 2nd display. But it couldn’t. I guess these 2 utilities don’t work totally orthogonal.
