I love having threads on Slack, but I absolutely hate that it always open in the right corner, instead of showing in the center. I always have to drag the border all the way to the left so it's not just a small column on the side
I agree. The Slack thread UX is not ideal, but the flow of conversation is so much better than it was pre-threads. I always end up closing the side bar and navigating to the thread in the "Threads" view. They should make it easier to maximize a thread.
At least this UX of Discord's makes it easy to do that: the article points out that opening the thread from the list below a channel will open it in the main chat view instead of the sidebar. At least from the article it does seem that Discord was paying attention to flaws in Slack's UX.
I genuinely hadn't realised you could resize threads to be wider and found it really annoying how narrow they were. I don't think I'd noticed any visual cues you could resize them either (assuming the cues exist).
