It's not that hard to deal with.

I have only two problems so far:
1:
When you delete all the messages in a stack and it automatically goes back to the main Messages screen the stack is still there and if you just click it it takes you to an empty stack. This is a bug from v6 that hasn't been fixed. Not that big a deal, just a little irritating.

2:
When you full-view a Deviation the ads now go over the deviation. This IS a big deal and damned near unforgivable. That's trying to force subscriptions through coercion.

The Layout changes are fine, however much people whine about it. You'll adjust. But something like problem no. 2 is NOT a minor thing... However it seems to have been caused by some downloading issues. I apologise to dA

Having checked now: I love how the Favourites are organised now...
