Everything seem to be neat but there is just one thing i couldnt bare with, please place play buttons icon just a bit right, i am sure it is in the center but since the left part is bigger it may seem better if it is near to right
Are the program starters on your first workspace? Or do you launch apps through something like dmenu? Where is the Jupiter descending feed coming from?
I use dmenu to launch programs. The Jupiter feed is coming from a local file, which contains rising and setting times for a few planets for the next year.
