  1. I will definitely be installing this theme on eOS, as I was starting to get bored with it.
    This should perk things up though.

    Nice website btw, just saw it today for the first time.

  2. on top left corner you got apple icon,I’ve done all of your tutorial,but I can’t change “appliction” into apple logo .thanks :)

    • go to your theme folder > open gtk-3.0 folder > open apps.css > and search .panel-app-button > add this code background-image:url(‘yourimage.png’); background-repeat:no-repeat; after padding.

      like this:

      .panel-app-button {
      padding: 6px;
      background-repeat: no-repeat;
