Hi,
I have created a small application that can hide the dock on selected virtual desktops. Let me remind you that by default you can only hide or show the dock on ALL virtual desktops.
In a more worded response: What happens when I click on the hyperlink present in your comment is that the URL isn't found. It's a little quick edit. I didn't have an issue going to your project on GitHub after highlighting the URL via text select, but you've made it a clickable hyperlink that doesn't go to where you thought it would go to.
