Priv Productivity tab update?

Noticed earlier the productivity tab has received quite a nice visual overhaul. I was just wondering when this happened? I upgraded to an iPhone a few months ago and haven't been using my Priv too often.

It also got me wondering though - what sort of things would you like to see improved / added to the productivity tab? I like it but have always found it a bit too laggy to feel nice using, but think it has potential to be a really nifty feature if properly optimised.
