How can I minimise applications by clicking on its icon on dock?

Question

Whenever I open a single folder and if I click on the Nautilus icon in the dock, it doesn't minimize it. Is there a way to do this?

Answer 1

If you mean 'minimize on click', you can activate this feature by running the following command:

gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'

After running this command, whenever you click on the icon of the folder/application, it will be minimized.
Here is a demo:

If you want to go back to the default settings, run the following command:

gsettings reset org.gnome.shell.extensions.dash-to-dock click-action
