I'm using Docky at the moment, and I love it. But what I really want to do is to be able to stack programs, like how you stack apps in a folder on an Android homescreen. So, for example, I have Spotify and Clementine and Rhythmbox pinned on my dock. I'd like to be able to stack those all into one icon that, when clicked, would expand to show all three.
I tried Docky Stacks but not only could I not get it to work, I don't think it would do what I wanted i.e, I think it just stacks folders, not programs.
Can anyone suggest a dock that can do what I want? Thank you.
