i have a gallery page with a dropdown to select gallery, i want this changed so each gallery has a thumbnail instead to select, then 2 columns changed to 3 in the galleries page - settings for these need to be editable in admin (maybe Gallery Settings page) in admin, i need a filter to filter each gallery when editing,sort order, pagination setting to change front end amount (Gallery Settings page), a sort order to manage what positions they display in (simple up/down arrows maybe) galleryname to be a dropdown to be able to move images couple of changes>remove image name and photo description change to caption
