I remember that in Windows one had the capability to make one's cursor have a trail, and there was a slider to indicate how long this trail would be. I believe that there was also something similar in the unity-tweak-tool, though I can't be absolutely certain of it.
Anyway, I am running Ubuntu GNOME 15.10 with GNOME 3.18, I can't find anything to achieve my objective of giving my cursor a trail in the gnome-control-center, nor in the gnome-tweak-tool, so I was wondering how exactly I am going to manage to do it? I've done a search through dconf-editor, but I can't find anything, though that does not necessarily mean that it's not there because there are a lot of settings there...
