Seems to be a great app. But here are a few suggestions I have for you. When you toggle off the top menu theres no way to close the menu screen, and I suspect that theres no way to get back to it either.
I would love if you would add the notification page under the favorites menu. This would be very useful when you are browsing in mobile view. Maybe even a way to edit the favorites menu and add our own links. For instance there are several groups Im heavily involved in with and would like to get to their page quickly.
