How do I remove the application icon from the top panel?

Solution 1:

/path/to/your/gnome-shell/theme/gnome-shell.css (default path is /usr/share/gnome-shell/theme/ )

Find there something simmilar to this: (it's on lines 3xx-4xx)

.panel-button #appMenuIcon {
        width: 0px;
        height: 0px;
}

.panel-button #appMenuIcon {
    app-icon-bottom-clip: 0px;
}

.panel-button:active #appMenuIcon,
.panel-button:checked #appMenuIcon,
.panel-button:focus #appMenuIcon {
    app-icon-bottom-clip: 0px;
}

.app-menu-icon {
   /* width: 24px;
    height: 24px; */
}

Alt+F2 -> r

That should remove the icon.

Solution 2:

Alternatively you can install "Elegance Colors" which holds the option for hiding the App-icon.

You only need to install it and uncheck the App Icon slider:

On this note I want to know why my other question was removed, I looked up the requirements in the help center and non of them applied, it was a different way and most importantly easier.
