I just gave it a go and played around with badges. When it comes to the usability I think the same points as in A redesigned 'Build' page - let me know your thoughts! - #7 by janfaracik do apply here as well. Common tasks need to more accessible as you already said.
Visually I am a little torn because I like the design but all of the sudden there is so much emptiness. So much room for activities one might think, but my god is that filter input wide 
It becomes hard to visually connect the build result / number / name / time with additional information such as badges or texts provided by plugins.
