(passwd : 0000) Message Search, auto-send, background image, other profile picture features

Hi,

First of all, I would like to thank you for creating this app. I really love the simple aesthetic, and the objective behind that app itself is very interesting. I'm currently using it !

I had a few things I had hoped this app had, but didn't. The ideas are as follows :

1. A feature that lets us search for a message : With this, we could find a message, even though we don't remember the day we wrote it. It could help to have it as a reminder of what we've thought.
2. Auto-send feature : We could set a future time on which we get a notification from the person we're supposed to talk, with a custom message. For example, I could make the person I'm talking to send a message at 4P.M. tomorrow, with the message I decided to give. Also, we could make it have a notification every day for example : looping the notification every 24 hours.
3. Background Image : a feature to add a background image.
4. Lastly, a feature that lets us give a profile picture to the other one we're talking to. We can give a profile picture to ourself, but not the other one.

Again, thanks for this app.
