Cadence

the second button is for rooms (gonna call them "channels to make discord users happy) that are not in a group (which will be most rooms - few people set up groups because they're so annoying, and many communities of people only need a single chatroom)
+
for now, please assume that current groups ("groups v1") will not be recognised by this client at all
+
so yeah, press the second button, you see all the ungrouped channels
