Thanks, we are keeping a note of all these issues and will make sure we add it to the list for our tech team to look at.

It does let you do last I think. If there are many pages you see 1 2 3 4 5 6 .. 29 30 or similar - the last two are always equivalent to last and second last iyswim. It's just not labelled "last". If you're in the middle pages of a long thread it should show something like 1 2 ... 17 18 ... 35 36 - so the first and last page links should be visible.
