Does Element have discord-style replies? This is the biggest feature missing in slack for me. Being able to quickly reply to a particular message that might be 2-3 messages behind goes a really long way in being able to maintain multiple flows of a conversation
Yes, it does, and has done for about 3-4 years.
I'm not sure an entirely separate mechanism is needed to achieve Zulip-style threading, though? Seems like the current thread design could easily be adapted to support named threads.
Does Zulip support nested threads?
Fun fact: the design for Element’s current threading is from a former Twist designer; make of that what you will :)
