[GIF] Tweetbot with a Hidden Tab Bar (concept)

Here I'm trying to apply my rough concept design for a hidden tab bar to an actual app, Tweetbot.

After several discussions about the concept, it was pretty obvious in real world scenarios, this might only work for single purpose apps where the user doesn't often switch context, if that.

Apps strongly based on feeds were the prime candidate, so I applied it to Tweetbot. The gif animation shows the context switching and the attached video shows the full interaction.

Open it up on your device to see how it feels. And let me know your thoughts.
