[FR] Auto page title + save spot + scrollbar + jump to heading + collapsible headings + icons/emojis

### Description

A few thoughts:
1. When you open a new page the page is 'untitled' until you select & edit it specifically vs Notion there's an automatic page heading you type in which also names the page itself.
2. When you're swapping between pages it automatically goes back to the top of the page, it would be nice if it remembered where you were
3. In needing to scroll back to where I was the scrollbar is a little too small to grab with the mouse easily
4. Having the little popup to jump to headings would also be nice, like in Notion
5. There's a dropdown text option but not with headings to show and hide sections
6. The full range of icons/emojis to use

### Impact

Just a few quality of life things that would be nice (or maybe the option to toggle) for the average user :)
