This re-design is a disaster in every respect. They've removed the ability to have mentions and reactions open in a sidebar, so now the messages pane stretches the full width of my enormous monitor. They've added an "Activity" thing which shows unread messages even when you're looking at the message it's telling you you haven't read. They've added a "Canvas" feature that is so useless that today the button for it turned blue with the words "Try this" because literally nobody is using it. They've added a "More..." button in the sidebar despite the fact that there's acres of empty space for those items. Huddles are the worst video calling experience available on any app, and yes, I am including Teams. I could go on and on, but Slack seriously needs to hire some good designers, I hate absolutely every aspect of having to use it now.
