Hipchat yes, but Mattermost didn’t really leave that bad of an impression. A bland SaaS chat.

Teams however… the search functionality where you can find the message but can’t jump to it so that you can see the rest of the conversation.

I actually scrolled up for some 5 minutes non-stop once trying to get to the conversation like that

I don't know how long ago you used teams, but that feature has been active for a while now. Since that was your main complaint, maybe you will like it now.

that was the cherry on top / the straw that broke the camel's back. Overall sluggishness and long loading times were probably the main problem. Zulip seems to be the endgame team messenger for us. Once you embrace the thread-first paradigm the old-school Slack/etc. single-thread approach is just too noisy.
