Requested feature overview description.
if a pool has many posts that span multiple pages, have an additional page selector before posts

Why would it be useful?
It's very mildly annoying to have to scroll down to the bottom of a pool to go to the last page of posts to get to one of the last posts when a long comic, say Tale of Tales, get an update (I prefer to read from the say 3rd last, to make sure I'm up to speed and that i don't accidentally only read the last if there were 2 updates close by, and I wouldn't be surprised if this was the case for others too).

What part(s) of the site page(s) are affected?
Pages of a pool

Alternatives:
> add a button to go to last page in Gallery view
> add a setting to automatically go to last page.
