Category Pages Changed

I just changed the looks on this site category page (you can also say it's an archive page but not like the archives page at the top menu of this site) .. and actually this idea is come after i visited the famous Matt Mullenweg site :-D

When i saw Matt category page (choose one of his site category and you’ll get the idea), i think it's a good idea to create it here also. Beside

At first i want to show my categories pages as paged with the previous and next button after displaying a specific number of posts on the categories page (i think it's not a good idea to show all posts from each category especially if you’re going to create a lot of posts in that category in the future which might cause performance loss)

Unfortunately because i don't know how to do it .. i think i’ll keep it like this for now ( I know most of you doesn't even care about this .. but i think i’ll post it anyway :-P )
