I have zero interest in these feature hiding, information density reducing ‘upgrades’. Nice hamburger menu, real innovation.
Maybe you'd like to make your own free(dom/beer) email client and see what positive responses people post there? :)
The hamburger menu was already there, it's not new. That's the point, I think.
It does make sense, because the list of emails typically requires the full length of your window. And while most emails may not use the full width of the window - some do; and one shouldn't have to open a separate window for those.

is the only way to go... for me. I realize that some people like it different and that's fine.We shall see. Apparently you can keep the legacy view anyway so everyone's happy.
