After generating management pages, how to customize them

I have generated with gii some CRUD pages for one of my tables.

I am wondering how can I customize the list how is displayed and add some visible filters, other than the advanced, also pagination should work somehow different.

No idea what you are asking for

This is the page the gii generator come up with. I want the layout customized, how can I do that?
