The shine has gone!
Even if I crank Global spec up to 100, only the blue cover gets some small white pixels.
"I am a road map, I will lead and you will follow, I will teach and you will learn, when you leave my sprint planning you will be weapons, focused and full of JIRA tickets, Hot Rod rocket development gods of precision and strength, terrorizing across the repository and hunting for github submits."
