Not sure if this should be considered a bug report or feature request, as the new replying feature only partially works, compared to the official client. Specifically, in Ripcord, replying in groups is fine, but replying in DMs is not possible (the menu item is greyed out). If this isn't intentional, this post would be a bug report; if it is intentional, this post would be a feature request. (There should be no reason to intentionally disable replying in DMs...)

In case it really is intentional, here's my rationale for why this feature should be included:

Reply in DMs is useful, as multiple topics could be discussed at the same time even with the same person, and reply could be used to indicate the specific topic that a message is discussing. It's also useful to reference an earlier message by replying to it (though this requires the "jump to replied message" feature that isn't implemented yet and already has a feature request here). I use it like this in Telegram all the time.

It will be in the next update.

Oops, forgot to add: this wasn't omitted intentionally, but I wanted to get that version out the door. There was already a long list of more things to do, and this just didn't make the cut.

Fixed in next release.
