Pin the Rooms to the Top

We occasionally want to send messages to a chat room, but if we have joined more and more channels and groups, it would be hard to find it soon.
For this purpose, we can pin the room to the top and have it available all the time.
It is as easy as clicking on the pin icon on each chat room in the main chat page.

Then if we enter our account using different devices, nothing differs and the pinned rooms are still on top.
