The navigation between profiles is sometimes quite annoying. Usually you need to use the upper left "<" to go back to the grid (either when in a conversation or flicking through photos or profiles).

In many applications swiping from left to right (at the middle of the screen) does the same trick and is much more convenient in contrast to using the "<".

It would be good if the left to right swiping would be applied consistently within the different sections of the App (from profile to profile / pictures within a profile or conversation) to come back to the Grid/overview.

Currently there seems to be an error in the logic as sometimes I am tapping on the "<" and it is like a loop - picture or text and it takes several tapping before you're back at the grid. Maybe you can verify if all code is at the right place.
