changing navigation/pager template

Hi,

I would like to do the following change to the navigator/pager template.

1. the albumpages from pager should be displayed in the middle/centered of the navigator items first/prev and next/last to the left and to the right. There is place enough between these two and I save the extra div/room taken by the standard pager line.

2. change the number of displayed pages by the pager. So more pages should be displayed and not only 1-8 then ... and the last one.

Maybe somebody did this already, or can help me to do that?

thx,
Bernhard
