Alllow returning messaging screen to bottom after scrolling up

Idea name: Alllow returning messaging screen to bottom after scrolling up
Description: Button that could be toggled and allows returning messaging screen to bottom after scrolling up.
Use case: As a user, I want to be able to scroll back to the bottom of a chat so that I can have a great experience using the chat.
Target user: Everyone…
Why this is important: Many times when people scroll up a chat, they do that because they find the conversation interesting and are trying to read previous messages on that conversation. After reading up, no one wants to read the same thing again, and currently you have to scroll and scroll to get down to the bottom.
Any other comments:

If you think this is a great idea and know how to implement it, consider posting a project proposal on Assemble.

It sounds like a very reasonable (and fairly simple) idea. I wonder what @hester have to say about it.
