Disaster

Please, return old version.
This one is disintuitive, Doesn’t allow be in two sheets through the tabs,
Switching between ‘rooms’ and PM chats is very uncomfortable and disturbing.
Message sound is terrible and new GUI has no settings where to modify it.
This environment is made exactly by motto: “Why to do things well, if is possible to do things much worse”
Instead, please keep motto: “Is something works well, don’t change it.”
