So I like this MacOS feature where your cursor displays in large. I was hoping if anyone knew of such software that replicates this functionality for Linux. Considering MacOS and Linux are both Unix, and libraries are different, could X or Wayland help replicate this?
KDE Plasma has a desktop effect called “Track Mouse” after you activate it you can use it by pressing Ctrl+Meta. It doesn’t look like the MacOS variant, but it does the job.
Thanks for pointing that out, I found the setting on my laptop and tried it out. I do like the jiggle approach better, though, simply because that is something many people (myself included) instinctively do when losing track of the mouse cursor.
I just added it because the current answer (jiggle) is a Gnome shell extension. So this is just my answer for Plasma.
