gnome-shell-extension-impatience - 0.4.8-2 main

The impatience extension allows you to speed up GNOME Shell
animation speeds.
.
From gnome-tweak-tool you can use a slider to scale the animation
speed down to any percentage. A speed scale of 1 means normal speed,
0.5 will result in animations twice as fast, 0.1 will result in
animations being 10x faster, etc.
