Being a long time Windows users, one thing that bugs me in GNOME is the location of the "Show Applications" button. When the dock is set to bottom, it is on the right hand side rather the left. There is no option in setting sto move this the left bottom corner.
After a bit of research, it seems the command below would fix my problem.
gsettings set org.gnome.shell.extensions.dash-to-dock show-apps-at-top true
At first, I find it odd as it sets the button to the top rather than to the left. Then, I remember the default layout of the dock is vertical. The button was on the bottom. Now setting the button to the "top" makes a lot of sense as when laying the dock horizontally, the left spot is what it was the "top" position when it was vertical.
Now the fix makes the dock perfect.
