Personally hate the change to the swipe. I get that on some huge servers people probably use the “reply” feature a lot, but I definitely don’t have so much use for it as to give up the nice, coherent and logical UX of “channel/server list is on the left, user list is on the right, just swipe to them”.
IMO, swiping should be for navigating UI, not interacting with individual items. Now there’s a useless thing on the swipe and I have to reach to the top of the screen if I want to check who’s online and in the channel. Annoying.
That and the new DM screen doesn’t use swipe right as navigation, it’s just a “back” button now. Can’t quickly look at the DM list and go back to your conversation by swiping right-left any more. Literal lazy design because this is an easier way to program that interaction.
Don’t care super much about the DM button moving, it’s more convenient to access but breaks the UI paradigm. Shrug.
Oh, and the “midnight” theme is not new, you could use it for years now in the old versions.
