If I've scrolled for a while there isn't really a good way to refresh my feed aside from closing out and relaunching. It would be kinda nice if you were 100 posts down and you press the homebutton it'd take you back to the top or just refresh and take you back to the top. I think a confirmation would be nice to have with it also just Incase it's accidentally hit.
The dots on the upper right can be hidden at times when scrolling.
I find going a post or two down the line then scrolling slightly up can make them reappear. Then you can use the refresh feature.
