Visual Changes in Workspaces/Service

[Trcose]

I noticed over the last couple of days that workspaces online have a new look without the colorful icons and quick tabs between reports/datasets. 

Is this a setting I've inadvertantly activated or a planned change to the online experience? I cannot find anything about it in the blog. I miss the quick color-coded organization from before.

This is the worst! Hoping I can find a setting in Admin to chnage it back.
