Seriously +1 but I'm out of votes due to the number of issues Microsoft caused with this forced update.
One of the reasons I've used this (and been a paying customer) vs Gmail is with a complex folder structure and using "Move to" (Top action bar) the nested folders remained open.
With this new format I have to reopen the sub folders every time and it's taking forever.
Absolutely, we are looking into this
Seriously, the new format is horrific
