gnome-shell extension to switch workspaces with a click

[Giacomo Montagner <mantager gmail com>]

Hi all, 
I was wondering of there is an extension that permits to switch to the 
above/below workspace with a click. For example, the dock extension 
could include two buttons, one at its top and the other at its bottom, 
that sends to the previous or next workspace (respectively). 

I'm asking this because I'm using Gnome on my tablet, and when I have 
no keyboard plugged in I have to go through 3 "clicks" in order to 
change workspace: click on "Activities", click on the right bar, click 
on the desired workspace. Since I rarely use more than two or three 
workspaces on the tablet, a fast switch would be appreciated (I tried to
do it myself but I'm afraid Gnome 5 would get released before I can sort
it out :) 

Any plan to implement this? 

Thanks, bye. 

Giacomo
