This is great, I'm a heavy G Suite user (I have folders with tens of thousands of messages) and I'm enjoying the beta: it scrolls like butter!!!! (or has teh speedy, as greybeard Mac users would say)

I miss some things, like keyboard shortcuts for jumping to a specific label, superstars, search items suggestion (for specific GMail filters like has:attachment), but overall this is really good, and honoring the label colors is an excellent touch.

Some more advanced features that come to mind would be multiple tabs, deeper Calendar integration to display inline your schedule when receiving .ics attachment.

What will the pricing model be?
