Once you add history to Slack, it's performance is just awful. One of the worst performing apps I use. It can take over a second to switch rooms. If I have to cycle through 4 rooms to get to the conversation I want, it can take seconds just to Option+UpArrow there. Plus I can't manually reorder rooms as I like. I don't get why everyone talks about the Slack UX. Slack has snippets. Which I find mostly useless. Especially since they kill performance. But HipChat lets you reorder rooms as you see fit. Which is something I actually used and miss desperately. At least Slack has finally gotten rid of the useless Channel vs Group distinction?
