The icons/theme can be changed, I had those icons and I just throw them there. For the workspace, I don't used it and I was kinda stuck there, but I like your idea.I like the dock, I like the 3D style, but yeah it should have the option to choose: 3D or flat and change the position.I had some ideas and some free time and I opened PS and made this. It's far to be perfect, I know it's nothing original, but maybe some people can get inspired by my work(also I'm not a pro, just an hobby).Thank you for your thoughts, take care!
