Feature request + feedback: Top nav menu behavior

First off, thanks for building this great app! I'm enjoying it a lot so far.

I have some feedback about the top nav menu which shows after tapping the word there, e.g. 'All', 'Home', etc.

• Subscriptions list: I'd love to be able to toggle the subscriptions list on/off, as I'm often using this menu to quickly toggle between All/Home/Local. For me it would be more helpful if these were recently visited communities. Note: I didn't realize this was a subscriptions list at first, or that it was scrollable
• Time to open: Currently it takes ~2 seconds to see the menu after tapping it. I'm hoping future releases will speed up the time it takes to open this menu!
• Navigation: After tapping one of the 3 top options, e.g. 'All' from 'Home', it opens as a view nested within the previous view, rather than toggling to the new view (requiring two taps to get back to Subscriptions)
• Keyboard bug: Keyboard stays open after tapping an option
