Idea for HN: DiggBar functionality?

Question: do you usually forget to "vote" for good links in HN?

I find out: a lot of times when i read HN, i click many links that i find interesting to new tabs in FF. Then, i go on to read all those. The problem is, after reading it, i usually forget to vote it because the voting functionality is back in the HN page (and i can't click back since it's new tab).

Sometimes i re-open the HN, look for that link, then vote it. But, i lose count on how many good links that i didn't vote or give comments.

Anyway, i thought it would be great if we can just vote and give comment on that actual news/blog page.
