[Plugin: NextGEN Gallery] Different options by gallery

Hello,

I have search several days for an answer to my “problem” but i can’t find anything. I’m a bit surprised because i don’t think i’m the only one who would like to do that : having a different style and options by gallery.
I don’t want all my galleries to be 4 columns for example. On some pages of my website i’d like them to be 5 and on other one 4, some will show all the images, others not, and so on…
Is there a way to do that?

Second point is that i’d like to do a slidesow with lightbox effect that will launch when i click on a picture.
I don’t want the slideshow to start on the page, and i like the lightbox effect.
For now i have written everything in html with a list of href with rel=”lightbox[any_name]”.
Is this can be done with NextGen Gallery?

Thank you in advance for your help :0)
