You know when you're texting someone and you think of something you need to say but they respond before you finish writing your text, so now you have to respond to their text but don't want to rewrite everything when you finally get a chance to change the topic? Maybe it's just me, but I'd love to have a feature where I could draft a text message in a conversation and then stash it while I continue that same conversation. Then later I'd just pop out the stashed text and send it.

Right now the closest option is to schedule a text out into the future, continue the conversation, and then unschedule and send the unsent message. but that's kind of a pain.

Maybe a good solution is to make the schedule feature into an unsent message stash, where messages have the option of having a send-time or not having a send-time. that fixes two issues with one change. The other issue being that unsent scheduled messages don't get lost and forgotten somewhere up in the conversation stream while they await delivery.
