Re-activate Zone-Shifting

The point is, if I don't need (to see) the data, i should not see it (being invisible, hidden). In this respect, your previous implementation was advantageous over similar apps (Telegram, etc.).

I don't see any reason why section- or zone-sliding (as previously) would not be implemented at least as an option available on user-level & executed with settings-toggle-button, as it only enriches the usability.

I have a tablet with big screen & I still find new restricted- or static-view troubling in the portrait mode, in lanscape too though, but especially on the phones with small screens.
