Ctrl + Tab to switch between chats
Allow me to switch between chats using traditional keyboard shortcuts that every single messaging app allows today. The use of Ctrl + Tab to go to the next active chat will allow me to be more efficient and not rely on my mouse/trackpad. It gets extremely annoying at times when I have about 15 people pinging me and I can hear my mouse clicks.
Please make it MRU chats. That's what we really need.
