Looks great! :) If parity with whatsapp is the goal here, as a follow up we can consider "bubbling up" the conversation in the conversation list when you exit the conversation. It's definitely a follow up if we want to implement it, this looks really nice :)

Should we modify the time?
I see other messengers show the time when the draft was created.
I'm not sure yet what time i expect there but i guess adapting to other messengers makes sense..?

Matches @nimishavijay's comment, but we currently lack a timestamp. Will add it in a follow-up and respect that timestamp in the sorting logic 👍
