[Plugin: NextGEN Gallery] number of galleries per page

Hi, is it possible to setup the number of galleries in an album to display on a page? I already have over 20 Galleries in a certain album and the number grows every week. It surely looks strange if there are over 100 galleries you have to scroll down at some day.

It would be nice, if there were something like an alphebatically index for galleries of an album which contains too many entries. An search option for NextGen would be helpful, too.
