Jump to the beginning of the Space option on

Jump to the beginning of the Space option on scroll up

When a space is created there is usually important information at the top of the Space that needs to be referred to occasionally.

Would be nice to have a option to goto beginning of space:

When scrolling up you get a Down Arrow to 'Click to scroll to latest message'

Would be nice to have up arrows to:
^ 'Click to scroll to last message'

^^ 'Click to scroll to Top or Beginning or Start or first Message' (Some wording like this)
