What I want more is columns in Slack so I can see conversations in multiple rooms without having to click back and forth on them whenever a new message pops up. It's annoying that I can only see one at one time when I have so much screen space.

They used to have scaling issues (maybe still do for certain userbase sizes) so it might not be feasible for them to effectively double the amount of real-ish time updates.

It would be really handy for informational channels where generally you're just interested in reading updates, not replying. Something like that could reasonably live in the right-hand sidebar. Taken a step further, it would be really cool to be able to specify an official informational/status sidebar channel to be paired with your channel. For example: a team channel with a build status channel linked to it by default.
