no "last page" button to go to the final page

I agree, but there is a known work-around.

If you enter some ridiculously high number -- like 10000 -- in the page navigation, it will back you up to the last page of the report.

I would rather want 'ascending sort' (thus seeing the last page metrics on top) instead of going to the last page.

Depends on your goal. It could be that you have several hundred entries with a value of "1"

In that case a reverse sort would (presumably) randomly select and number some of the "1"s as 12345... and you would still have no idea how many unique values were recorded.

and it could be possible to sort by the line, like pagename, products, campaigns, ...

What about the option of "Show All" where you can simply let the data be on one page?  I understand paging could be necessary from a processing/rendering perspective, but most of the time I'd like to see the whole thing to make comparisons (I think most users can understand it will increase the display time, pretty formatting be damned).
