So the Wall is gone from the top navigation on mobile screens, and its nav button will eventually be removed altogether. The Wall content now lives right on UMD's homepage at the bottom.
On the homepage, eventually I *may* remove What's New (already now on the Sites homepage) and Top Store etc (already now on the Store (formerly Downloads) homepage). The goal is to get the homepage to act more like a normal social media "Home" where you just go to the site and see a feed of latest activity that you can infinitely scroll through.
Also on mobile sizes, the pulldown nav menus will no longer exist. I hope that people will like / get used to the new hamburger menu.
There are a ton of other little changes I've been making over the past couple of months that I just pushed live this morning, so thanks for your patience with me while I continue to work on it and listen to feedback.
