Honestly I use an app called zellage and I like being able to put my music player(cmus) and artwork ripper(cmus-art), and usually a visualizer (wtf can't I remember it's name).
There's no particular advantage so much as my personal preference for staying on keyboard and off mouse. I have everything bound to key chords that I've more or less memorized so it's a quick ctrl+t n for new tab ctrl+p v move pane down , etc etc and I can do all of it more or less by feeling.
It's largely an aesthetic preference, but It's also that I have a slow system. So I can keep ram use down. 2nd gen core i3 problems (shrugs)
Yup that's the program
