I like the aesthetic changes to the UI, it definitely looks more modern and less cluttered. But it's the severe cut in features that annoys me.

* No way to easily access personal multi-reddits

* Saved/Hidden/Blocked have disappeared

* A lot of information in the subs sidebar doesn't show up anymore (things like related subs, wiki and so on). Now it's limited to rules and welcome message.

The multi-reddits thing is especially problematic to me. If you've subscribed to many subs, it becomes unmanageable without them.
