navigating posts

a few weeks ago i asked in this forum how one was to navigate through older posts under edit in wp-admin. i did not receive much of an answer so here i go again…
in the wp 1.1 beta i had installed, when clicking edit all i received was a simple search form, but no more other navigational features such as “view last x posts”, search-by-date or search-by-category features.
please check out this img to understand what i mean…
now i discovered in the latest wp screenshots here that this was not a mistake but for some reason intended…
but i need and use those other navigational features often.
especially when trying to clean up my comments from spammers.
for some reason the comments load in the wrong order, [how can i fix that?] showing the very first comment ever posted to my blog back when i started it on top. the search form is simply not enough to navigate comments.
questions:
why were the other navigational features taken out?
is there a technical reason, a bug maybe?
is there a hack for this?
how can i build them back in?
