Improve "Load more" functionality for long PRs

[IvanPizhenko]

I have a PR with lots of comments and commits... And so I get something like this:

Each time I click it it loads some more stuff, but.... from the beginning, i.e. if there are N items in total and 1 to M were displayed so far, when I click "load more", it show me 1 to M+K items.

Improvement 1. I wish it could have functionality where there would be 2 links (below and above "X hidden items"), and when I click the upper one, it works as now, but when I click the bottom link, it would show items 1... M, then this "X hidden items", and then items N - K to N.

Improvement 2. It also would be good to have there link called "Load all", so I can load all at once if I wish so instead of multiple times clicking "Load more", waiting time after each such click...

Please consider implementing at least first one. Thanks in advance...

Agreed, handling long PR is sometimes painful because of this, it is not easy to find the comments we're working on

But overall I think this feedback shows that currently long PRs are not well handled with this very linear reviewing process
