So you want them to be invisible in a way.

Yes.

And in order to do that, it...

you have to overcome even more challenges.

For example, you mentioned this deletion effect, message evaporates.

If you do the animation, if you show the animation first, and then the message that is preceding the deleted message that is going after the just deleted message move closer to each other, then it doesn't feel right.

It feels too long, too imposing.

So what you want to do is you want the message disappear while the messages around it go closer to each other to fill the resulting gap.

And then you imagine what it involves.

Redrawing the entire screen.

So on top of this very complicated animation,

You have to think about things like which kind of messages were there before, after.

That just adds to complexity.

But you know, once you accomplish it, it gives you this immense sense of pride.

Because nobody is doing this.

Nobody really cares.

In a way, maybe they're right not to care.

Maybe nobody notices this, but there is something about it that feels wrong when such things are neglected, because I understand that every day tens of millions of people around the world are deleting messages.

What kind of experience do they get?

Is this an experience that maybe even subconsciously inspires them and makes their heart sing even a little bit?
